The High Pressure Synthesis and Properties of La0.3Sr0.7CrO3
【摘要】 采用高压高温方法合成了单相的带宽调控型La0.3Sr0.7CrO3Mott化合物,对其晶体结构和磁学性质进行了研究。结果表明:La0.3Sr0.7CrO3化合物具有立方钙钛矿晶体结构,温度在170K以上其磁性为顺磁性,满足居里-外斯定律,温度低于20.7K发生了自旋玻璃转变。
【Abstract】 We synthesized La0.3Sr0.7CrO3 Mott compound by using high pressure and high temperature sintering method;and studied the crystal structure and magnetic properties.It is shown that La0.3Sr0.7CrO3 adopts a cubic perovskite structure at room temperature.Above 170 K La0.3Sr0.7CrO3 is paramagnetism with the χ(T) curve being fitted by Curie-Weiss law,while a spin glass transition was found in La0.3Sr0.7CrO3 below 20.7 K.
