在4.2-300 K温度范围内，研究了脉冲激光沉积法制备的Pr_（0.65）Ca_（0.35）MnO_3薄膜的电阻随温度的变化关系。结果表明，在反铁磁有序温度TN的区域内，电阻随温度的变化出现突变。实验数据进行了分析的框架内的现代理论概念的运输机制和钙钛矿锰氧化物。
Temperature dependence of resistance of Pr0.65Ca0.35MnO3 thin films prepared by pulsed laser deposition method are studied in the temperature range 4.2–300 K. It is shown that an abrupt change in the temperature dependence of resistance is observed in the region of antiferromagnetic ordering temperature TN. The experimental data are analyzed in the framework of modern theoretical concepts concerning the transport mechanism and perovskite-like manganites.
