Аннотация:New diluted magnetic semiconductors (CdGeAs2:Mn, ZnGeAs2:Mn and ZnSiAs2:Mn) chalcopyrites were synthesized. Magnetization M, electric resistance, magnetic resistance, and the Hall effect of these compositions were examined. Athough they are complicated, the M(T)curves are similar in shape, due to the concentration and mobility of of the chare bearers. their Curie points are higher than 300 K, the highest in systems of the A(II)B(IV)C(V)2:Mn type.
