采用共沉淀法制备了Gd掺杂的LaFeO3多晶样品。对La1− xGdxFeO3系统的结构、磁性和电学性质进行了详细的研究。Gd和La的离子半径和电子组态的不同导致晶体结构的畸变。我们把它与磁和电性质的发展联系起来。此外，我们提供了微观结构的影响。通过XRD、IR和磁性分析，推测了八面体位倾斜的系统变化。
Gd-substituted LaFeO3polycrystalline samples were prepared by the co-precipitation method. A detailed investigation of the structural, magnetic, and electrical properties of the La1−xGdxFeO3system was performed. The differences of the ionic radius and the electron configuration between Gd and La cause the distortion of the crystal structure. We have related it to the development of the magnetic and electrical properties. In addition, we provide the effect of the microstructure. The systematic variation of the octahedral-site tilting have been deduced by XRD, IR, and magnetic properties.
