Аннотация:Based on Mn-doped chalcopyrite ZnSiAs2 the new dilute magnetic semiconductor with p-type conductivity was produced. The Curie temperature behavior of the produced semiconductor is distingly dependent on the Mn concentration: 325 K for 1 wt.% and 337 K for 2 wt.% of Mn consequently. Magnetization. electrical resistance, magnetic resistance and Hall effect of mentioned compositions were studied. Temperature dependence of magnetization M(T) have complicate behavvior. For T < 15 K the M(T) dependence is characteristic for superparamagnetic and at T>15 K magnetization is sum of magnetizations of ansemble of superparamagnetic clusters and ferromagnetic phase contained frustration regions.
