Description

Technical Field

[0001] The present invention relates to the technical field of sample placement design, and in particular to a method for designing a universal sample carrier for measuring under a magnetic field and a method for using the same. Background Art

[0002] The design and usage of a sample carrier for measurement under a magnetic field designed in this design can fix and detect samples of different shapes and sizes to be tested, and is a key design to ensure the testing of samples to be tested. Conventional sample placement designs include sample placement designs such as sample stages and sample placement boxes. The above-mentioned detection method is multi-purpose and single-purpose when used, and is often used to place samples of a certain size. Therefore, it is not possible to perform efficient fixed detection for samples of different sizes and shapes to be tested. This design can detect a wide range of sample sizes and shapes, and this sample placement design is mainly suitable for sample magnetic detection such as sample magnetic detection of a vibrating sample magnetometer. In order to facilitate the detection of samples of different sizes and shapes, a sample carrier design and usage for measurement under a magnetic field is required. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art solutions, the present invention proposes a sample carrier and usage for measurement under a magnetic field, which can effectively solve the problems raised by the background technology.

[0004] The specific design scheme adopted by the present invention is as follows:

[0008] (3) Design a sample boat device, wherein the sample boat is a cylindrical structure body with a circular cross-section similar to that of a transverse cylinder, with the bow and stern of the boat retained at both ends of the cylinder, so as to be designed to fit into the hollow sample placement area and prevent movement; the body of the sample boat (i.e., between the bow and stern) is designed to be semi-cylindrical, and the other half of the cylinder is hollowed out, and the hollowed-out bottom of the boat is in a flat form, which serves as the sample placement area of ​​the sample boat;

[0009] (4) The hollow sample placement area that is hollowed out in a circular shape in the center of the sample rod has long and narrow grooves hollowed out in the longitudinal direction above and below, which are used to insert thin film sheet samples.

[0010] Preferably, the cylindrical rod-shaped sample rod body, the hollow sample placement area with a transverse cylindrical through-hole and the cylindrical sample boat described in condition 1 are exemplified by a cylinder, but may also be in the shape of a square column, a diamond column or an equilateral polygon column, but are not limited thereto.

[0011] Preferably, the cylindrical size of the cylindrical rod-shaped sample rod body may be the same as or different from the cylindrical size of the hollow sample placement area of ​​the transverse cylindrical through hole and the cylindrical sample boat.

[0012] Preferably, the hollow sample placement area in the center of the sample rod body has longitudinally hollowed-out elongated grooves above and below, and the specific depth and width of the elongated grooves are not limited.

[0013] Preferably, the length ratio of the bow, stern and body of the sample boat to the length of the cylindrical sample boat is not restricted.

[0014] Preferably, the material used for each part of the sample rod should be a non-magnetic material or a very weak magnetic material that does not affect magnetic detection, and is easy to process but not easy to deform, such as plastic, polymer material, glass, aluminum metal, etc., and the specific material is not limited.

[0015] A method for using a sample carrier for measuring under a magnetic field, characterized in that the universal sample rod design can be used in the following ways as a way to place a sample for magnetic measurement, including:

[0016] (1) The three-dimensional sample is directly placed in the hollow sample placement area for measurement, or the screws can be screwed vertically to fix the three-dimensional sample;

[0017] (2) After the powder or liquid sample is placed in a small container, it is placed in the hollow sample placement area and fixed, or the small container for placing the sample is fixed by screwing it vertically;

[0018] (3) The thin film-shaped sample is placed in the sample placement area and fixed in the sample placement area by placing the sample boat bottom plane horizontally or vertically into the hollow sample placement area to obtain magnetic moment measurement results in various placement methods;

[0019] (4) The three-dimensional sample is placed in the sample boat device on the bottom of the boat and fixed, and the bow and stern of the boat are added to prevent the sample from moving;

[0020] (5) The large-area thin film sample is placed in the longitudinally hollowed-out elongated grooves above and below the hollow sample placement area and fixed. The upper and lower grooves can fix the thin film-like object to be tested.

Different placement methods can be used to fix and detect samples of different sizes and shapes. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with specific embodiments to clearly and completely describe the technical solution of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0036] Embodiment 1

[0037] like Figure 1-Figure 3 As shown, this embodiment takes a spherical three-dimensional sample placed on a sample carrier for magnetic detection as an example, and includes the following steps:

[0038] 1. Place the spherical three-dimensional sample directly in the hollow sample placement area of ​​the transverse cylindrical through-hole of the sample rod body.

[0039] 2. After placement is completed, screw the screws at the bottom of the sample stick body vertically to clamp the three-dimensional sample for fixation.

[0040] 3. After placement and fixation, place the sample stick with the sample into the instrument for magnetic detection.

[0041] Embodiment 2

[0042] like Figure 4-Figure 7 As shown, this embodiment takes a sample in the shape of a small-area thin film as an example for magnetic detection, and includes the following steps:

[0043] 1. Place the sample in the shape of a small film in the sample boat device placement area designed to match the sample stick. After placement, use non-magnetic glue to adhere and fix the sample to be tested to the sample boat device.

[0044] 2. After the adhesive fixation is completed, place the sample boat device containing the sample to be tested into the hollow sample placement area of ​​the transverse cylindrical through-hole of the sample rod body so that the two are tightly clamped, or the screws at the bottom of the sample rod body can be screwed up longitudinally to clamp the sample boat device for fixation.

[0045] 3. After placement and fixation, place the sample rod with the sample into the instrument for magnetic detection. Since the sample boat device is designed in a semi-cylindrical shape, the detection angle of the sample to be detected in the sample boat device can be changed by adjusting the angle at which the sample boat device is placed, thereby obtaining different magnetic detection results.

[0046] Embodiment 3

[0047] like Figure 8-Figure 9 As shown, this embodiment takes a sample in the shape of a large-area thin film as an example for magnetic detection, and includes the following steps:

[0048] 1. Place the larger film-shaped sample in the longitudinal hollowed-out elongated grooves on the upper and lower hollow sample placement areas of the sample stick body to fix it. The upper and lower grooves can fix the film-shaped object to be tested. Alternatively, you can also screw the screws on the bottom of the sample stick body longitudinally to clamp the bottom of the film sample for fixation.

[0049] 2. After placement and fixation, place the sample stick with the sample into the instrument for magnetic detection.
