Abstract

The invention relates to the technical field of an in-situ physical property test and discloses an in-situ physical property test system and a sample mounting method. According to the in-situ physicalproperty test system provided by the invention, vacuum equipment is connected with vacuum sample preparation equipment; in the vacuum equipment, a sample is placed into a vacuum test cavity and the vacuum test cavity is sealed; a vacuum test part is connected with an insertion rod assembly; the insertion rod assembly is in sealed connection with a rapid sample injection chamber; the rapid sampleinjection chamber and a dilution refrigerator are communicated through adoption of an insertion plate valve; and the insertion rod assembly is controlled to act, thereby pushing the vacuum test part into the dilution refrigerator for a sample test. Accuracy when the in-situ physical property test system is used for characterizing a physical property is ensured. A physical property characterizationrequirement under all extreme conditions related to the dilution refrigerator are satisfied. The problem that according to a characterization test depending on the dilution refrigerator, a sample loading and unloading process is exposed to air is solved. An original high-intensity magnetic field and ultra low temperature environment of the dilution refrigerator is completely reserved.

Description

technical field

[0001] The invention relates to the technical field of in-situ physical property testing, in particular to an in-situ physical property testing system and a sample installation method. Background technique

[0002] The design, preparation and characterization of quantum materials is an important research direction of "quantum control". The traditional method is to try many different materials to find the one that meets the needs, but this method has the defects of long cycle and low efficiency. To this end, existing methods are based on a deep understanding of material structure and physical properties, and materials are designed and prepared according to requirements to achieve precise manufacturing. However, as the dimension of the material decreases, the proportion of atoms on the surface of the material increases, and the exposure to the atmosphere will have a huge impact on the intrinsic properties of the material.

[0003] Vacuum interconnection is re...
