Mn_xZn_(1-x)Fe₂O₄ ferrites where x is 0.75(μ₁=2000) and 0.52(μ₁=7000) respectively, were prepared at 1360 ℃ by sintering under N₂ atmosphere. The ferrimagnetic resonance(FMR) spectra of those polycrystalline samples have been studied to investigate the origin of physical process which results in permeability enhancement. In the FMR spectra of above samples, one intense peak preceded by two weak subsidiary resonance peaks were observed at room temperature. However, these two subsidiary peaks were disappeared near Curie point in each case indicating that the structure is cubic. The temperature dependence of the g-value, ferrimagnetic reasonance linewidth(△H) and intensity in Mn_xZn_(1-x)Fe₂O₄ ferrite samples have been also studied with the temperature dependence of the initial permeability(μ₁). The result showed that FMR linewidth(△H) and intensity are related to initial permeability.
