Abstract

The invention provides a magnetic resonance mutation spectrum material and a preparation method thereof, and in particular, the preparation method of the magnetic resonance mutation spectrum material comprises the following steps: 1) sample loading: iron platinum powder is put in an induction composite heating powder preparation device containing a heat resisting crucible; argon is charged after vacuumizing; and the pressure of the argon is kept at 1 KPa; 2) melting: a high-frequency induction power supply is started for heating to melt the iron platinum powder; and the input power is 10 KW; and 3) irradiation:an ultrasonic source or an ultrasonic wave-laser composite source radiation source is leaded in to adjust a distance between an argon shielding gas nozzle and a molten metal level as 20-25 mm to obtain black powder, namely the magnetic resonance mutation spectrum material. The magnetic resonance mutation spectrum material with different crystal form ratios is obtained through changing a laser-induction composite heating powder preparation device.

Description

technical field

[0001] The invention relates to the field of magnetic resonance materials, in particular to a magnetic resonance material and a preparation method thereof. Background technique

[0002] NMR applications can basically be divided into two categories: one is NMR spectroscopy (spectroscopy); the other is NMR imaging (scanners). Both types of applications require a strong and stable magnetic field B0. They are based on common physical and mathematical principles, and share many data acquisition and data processing technologies, but the application focus and ultimate goal of the two are different. To avoid confusion, using academic and industrial terminology, in the description of the present invention, "NMR" stands for nuclear magnetic resonance spectroscopy (Nuclear Magnetic Spectrometer), and "MRI" stands for Nuclear Magnetic Resonance Imaging (Nuclear Magnetic Scanner). NMR is often used in chemical, physical and pharmaceutical laboratories to obtain the nucl...
