Abstract: We have successfully synthesized a novel diluted magnetic semiconductor (Ca1−2xK2x)(Zn1−xMnx)2As2 with decoupled charge and spin doping. The substitutions of (Ca2+, K+) and (Zn2+, Mn2+) in the parent compound CaZn2As2 (space group P${\overline 3}$m1 (No. 164)) introduce carriers and magnetic moments, respectively. Doping only Mn into CaZn2As2 does not induce any type of long range magnetic ordering. The ferromagnetic ordering arise can only when K+ and Mn2+ are simultaneously doped. The resulted maximum Curie temperature reaches ~7 K, and the corresponding coercive field is ~60 Oe. The transport measurements confirm that samples with K and Mn co-doping still behave like a semiconductor.

Key words: CaZn2As2, ferromagnetic ordering, Curie temperature, diluted magnetic semiconductor
