| 摘 要： | 利用固相反应法制备了(La0.9Bi0.1)2/3Ca1/3MnO3样品,研究了它的导电特性和磁性.在电阻和磁化测量中观察到热滞现象. 在电阻-温度(R-T)曲线中出现了两个峰,当施加5T外场时,电阻中的热滞现象被抑制,只观察到一个峰.磁化(M-T)曲线表明,在居里温度(Tc)以下发生了顺磁-铁磁(PM-FM)相变. 样品不同寻常的M-T行为能够很好地解释测量到的R-T曲线.

| Abstract: | (La_(0.9)Bi_(0.1))_(2/3)Ca_(1/3)MnO_3 manganite perovskite was synthesized by solid state reaction and the magnetic and transport properties were measured.A considerable thermal hysteresis in resistance and magnetization has been observed,and two peaks occur in R-T curve.After applied 5 T field,the thermal hysteresis in resistance is suppressed,and only one peak can be observed.The temperature-dependent magnetization(M-T) curve shows that below the paramagnetic-ferromagnetic transition temperature T_C,a ferromagnetic-canted ferromagnetic transition may occurred.The anomalous temperature-dependent behavior of magnetization may account for the thermal hysteresis of resistance. |
