Abstract

The polycrystalline ferrites (Li_0.50Fe_0.50) _0.70Zn_0.30 (CuTi_1-xZr_x)_0.20Fe_1.60O ₄ with x=0, 0.25, 0.50, 0.75, and 1.00 were prepared and investigated. The X-ray diffraction spectra, the temperature dependence of saturation magnetic moment, the frequency dependence of ferromagnetic resonance (FMR), and the room-temperature Mossbauer spectra of these samples are measured and discussed in terms of the theory of ferrite physics and FMR. FMR line-widths varied with frequency very differently above and below 6 GHz. The room-temperature Mossbauer spectra can be resolved into five sets of magnetically ordered sixlet subspectra and one set of paramagnetic doublet spectra
