Abstract
The results of an experiment on studying the features of the crystal structure and magnetic studies of substitutional solid solutions of the Ni1–xCrxMnSb system (0 m х m 0.2) are presented. It was found that an increase in the concentration of chromium in solid solutions does not lead to significant changes in the size of the unit crystal cell. It was found that solid-phase quenching can be used to expand the limit of chromium solubility in Ni1–xCrxMnSb solid solutions. The temperature and field dependences of the specific magnetization of the synthesized compositions have been studied. It was found that the substitution of chromium for nickel in the NiMnSb compound leads to a decrease in the temperature of the “magnetic order – magnetic disorder” phase transformation with an increase in the concentration x from 0 to 20 mol.%. The values of specific magnetization and Curie temperature of hardened hard rasters are higher than those of slowly cooled ones. The results obtained contribute to the creation of a physical basis for the elemental base of spintronics.
