Аннотация:Conditions and mechanisms of controlled variation of the magnetic anisotropy by means of annealing have been determined for GaMnSb films containing MnSb nanoparticles. For this purpose, the temperature and magnetic-field dependences of the magnetic moments of samples before and after annealing were measured using a SQUID magnetometer. It is established that the heat treatment of GaMnSb films leads to a significant values of characteristics determined by the magnetic anisotropy, including the growth of blocking temperature (from 95 to 390 K) and the magnetic anisotropy field (from 339 to 630 Oe).
