| 中文摘要 | Electrical and magnetic transitions in Pr1-xSrxMnO3 and Pr1-xSrxMn0.95Fe0.05O3 ceramic samples with x = 1/4, 3/8, and 1/2 have been investigated. It is proved that 5% Fe doping in the system suppresses electrical conduction and ferromagnetism severely, but favours antiferromagnetism. The existence of spin clusters at temperatures above the ferromagnetic transition T-C is demonstrated in the Fe-doped x = 1/2 sample, which is caused by the Fe-doping-induced magnetic inhomogeneity. The transport behaviour above T-C in this sample is governed by variable-range hopping of the magnetic polarons. For the Fe-doped x = 1/4 sample, the insulator-to-metal (I-M) transition drops behind T-C by nearly 80 K; accordingly, two magnetoresistance peaks appear. One is around T-C, and the other lies just at the I-M transition temperature. The possible underlying mechanism is discussed qualitatively. |
