摘要: Recently a new diluted magnetic semiconductor, (Ba,K)(Zn,Mn)2As2 (BZA), with high Curie temperature was discovered, showing an independent spin and charge-doping mechanism. This makes BZA promising material for spintronics devices. We report the successful growth of single crystal first time in this study. An Andreev reflection junction, which can be used to evaluate polarization, fabricated based on crystal. A 66% polarization obtained by spectroscopy analysis.
