Colossal Magnetoresistance Effect and Magnetic Properties of La 0 7 Ba 0 3 Mn 1- x Mn x O 3
【摘要】 采用溶胶-凝胶工艺制备La0.7Ba0.3Mn1-xFexO3化合物.研究其磁性、导电性和磁电阻效应.结果表明,随着Fe含量的增加,电阻率增加,铁磁居里温度近似线性下降
【Abstract】 La 0 7 Ba 0 3 Mn 1- x Fe x O 3(0≤ x ≤0 12) was prepared by the sol gel technique. The effects of Fe doping on the magnetic property, conductivity and magnetoresistance for La 0 7 Ba 0 3 MnO 3 were investigated. The experimental results indicate that with increasing the Fe content, ferromagnetic ordering temperature decreases and the resistance increases.
