Diluted magnetic semiconductors (DMS) have received much attention due to their fantastic physical properties and applications for spintronic devices since the discovery of (Ga,Mn)As film by H. Ohno in 1990s. In this talk, we report a new kind of DMS materials with decoupled spin and charge doping. We use flus method to grow the single crystal DMS (Ba,K)(Zn,Mn)₂As₂ and (Ba,Na)(Zn,Mn)₂As₂ (BZA) for the first time^[1]. We also did a very systematic study, including the magnetic susceptibility testing, transport measurements,Xray Magnetic CIRcular Dichroism research, Andreev Reflection experiments and angle-resolved photoemission spectroscopy (ARPES)^[2-6], etc.
