A new diluted magnetic semiconductor (DMS) system, (Sr3La2O5)(Zn1−xMnx)2As2, has been synthesized and characterized. 10% Mn substitution for Zn in bulk form (Sr3La2O5)Zn2As2 results in a ferromagnetic ordering below the Curie temperature, . (Sr3La2O5)(Zn1−xMnx)2As2 has a layered crystal structure identical to that of 32522-type Fe-based superconductors, and represents the fifth DMS family that has a direct counterpart among the FeAs high-temperature superconductor families.
