Abstract: Dilute magnetic semiconductors based on manganese-doped Zn<subscript>0.9</subscript>Cd<subscript>0.1</subscript>GeAs<subscript>2</subscript> solid solution with various doping levels were synthesized. Their Curie point in 5-T magnetic field was 349 K. Ferromagnetic ordering in these semiconductors was due to MnAs nanoclusters, whose sizes were 3.7–3.8 nm. [ABSTRACT FROM AUTHOR]
