摘要：

We investigate the chemical pressure effects on the ferromagnetic ordering in magnetic semiconductor (La0.9Ca0.1)(Zn0.9Mn0.1)AsO by isovalent substitutions of Sb for As and Y for La, respectively. X-ray diffraction measurements indicate that Sb substitution for As expands the lattice and introduces negative chemical pressure into the system. On the other hand, Y substitution for La reduces the unit-cell volume, and improves the Curie temperature by ~& nbsp;30% at the doping level of 7.5%.
