摘　　要：结合实际工作 ,具体研究了改善某微波器件用旋磁镍铁氧体材料的铁磁共振线宽的有效方法。以少量 Co代替 Ni使镍铁氧体材料的磁晶各向异性常数近似趋于 0 ,以此来降低镍铁氧体的铁磁共振线宽 。Integrating study with practical work, some effective methods to improve the magnetic field intensity range of ferromagnetic resonance (Δ H ) of nickel ferrite used in one microwave device are studied In this paper we focus on doping Cobalt oxide to substitute cobalt cation for parts of the nickel cation in nickel ferrite in order to reduce the crystal anisotropy constant of the nickel ferrite material approximately to zero inclining to lower the Δ H of NiFe 2O 4 in the hope of meeting the consumers′ demands

关 键 词：铁磁共振线宽 镍铁氧体 磁晶各向异性常数 微波器件 CO
