Effects of chemical pressure on diluted magnetic semiconductor (Ba,K)(Zn,Mn)2As2 |
(a) The crystal structure of (Ba,K)(Zn,Mn)2(As1−yPny)2. (b) PXRD patterns of (Ba0.7K0.3)(Zn0.85Mn0.15)2(As1−yPny)2 (Pn = Sb and P; y = 0.1 and 0.2). The mark star stands for antiferromagnetic impurity MnAs, the solid diamond for nonmagnetic As, and the open diamond for nonmagnetic Zn3As2. (c) Lattice constants and cell volumes of the samples in panel (b). |
