摘要：

The structural and magnetic properties of Y2−xSrxCoMnO6 (0 ≤ x ≤ 0.5) compounds are investigated in this report. X-ray photoelectron spectroscopy reveals that Co and Mn ions are presented in the form of Co2+/Co3+ and Mn3+/Mn4+, respectively. The broadening of Raman spectra suggests the existence of antisite disorders in these double perovskite oxides. The ferromagnetic transition temperature slightly increases with Sr doping, while the saturated magnetic moment shows a substantial decrease, further confirming the presence of Co/Mn antisite d...
