中文摘要	We report the ferromagnetism with Cure temperature T (c) at 230 K in a new diluted magnetic semiconductor (DMS) (Ba0.7K0.3)(Zn0.85Mn0.15)(2)As-2 isostructural to ferropnictide 122 superconductors synthesized via low temperature sintering. Spin is doped by isovalence substitution of Mn(2+)for Zn2+, while charge is introduced by heterovalence substitution of K1+ for Ba2+ in (Ba0.7K0.3)(Zn0.85Mn0.15)(2)As-2 DMS, being different from (Ga,Mn)As where both spin & charge are induced simultaneously by heterovalence substation of Mn2+ for Ga3+. The (Ba0.7K0.3)(Zn0.85Mn0.15)(2)As-2 DMS shows spontaneous magnetization following T (3/2) dependence expected for a homogeneous ferromagnet with saturation moment 1.0 mu (B) for each Mn atom(.).
