| 中文摘要 | Effects of pressure, magnetic field, and Mn-site doping on the magnetic structure and resistive behavior of La-0.5(Sr0.53Ca0.47)(0.5)Mn1-xFexO3 (0less than or equal toxless than or equal to0.10) have been experimentally studied. The system experiences two magnetic transitions subsequently with decreasing temperature: a paramagnetic to ferromagnetic transition and a ferromagnetic to antiferromagnetic (AFM) transition. The second magnetic transition coincides with a steep resistivity jump. In addition to reducing the critical temperature for the AFM transition (T-N), the incorporation of Fe enhances the ferromagnetic order below T-N as demonstrated by the gradual increase of magnetization with the content of Fe. Long-range AFM order is replaced by short-range AFM order when x exceeds 0.03, and disappears completely for x>0.06. The application of pressure or magnetic field depresses the AFM nature of the compounds, resulting in a downward shift of T-N at a rate of similar to7 K/GPa or similar to4 K/T. The most interesting observation of the present study is the greatly enhanced resistivity jump at T-N, which increase from 1 to 2 orders, after the sample undergoes a pressurizing and then a pressure relieving process. Although high pressure, magnetic field, and Fe doping produce similar effects on the AFM order, the underlying physics is different. (C) 2002 American Institute of Physics. |
