通过铁磁共振（FMR）方法对四方相 CuFe2O4 铁氧体单晶进行了详细研究。在不同晶体学方向上测量了共振场和 FMR 线宽的温度依赖性，并由此确定了各向异性场和 g 因子分量的温度依赖性。分析了不同机制对四方相CuFe2O4磁晶各向异性的贡献。四方铜铁氧体被证明具有易平面型磁晶各向异性。
Detailed investigation of single crystals of the CuFe2O4ferrite in the tetragonal phase by the ferromagnetic resonance (FMR) method were performed. The temperature dependencies of resonance field and FMR linewidth were measured in different crystallographic directions, and from them the temperature dependencies of anisotropy fields andg-factor components were determined. The contributions to the magnetocrystalline anisotropy of CuFe2O4in the tetragonal phase due to different mechanisms were analysed. Tetragonal copper ferrite was proved to have an easy plane type magnetocrystalline anisotropy.
