Abstract

New diluted magnetic semiconductors (CdGeAs2:Mn, ZnGeAs2: Mn, and ZnSiAs2: Mn chalcopyrites) were synthesized. Magnetization M, electrical resistivity, magnetoresistance, and the Hall effect of these compositions were examined. Although the M(T) curves are complicated, they are similar in shape, for which the concentration and mobility of the charge bearers. Their Curie points are higher than 300 K, the highest in systems of the A II B IV C V2 : Mn type.
