【Abstract】 The magnetic properties, ferromagnetic resonance (FMR) and Mossbauer effect of Y1.2Gd1.2Ca0.6V0.3InxPe4.7-xO12 with x=0, 0.2, 0.4, 0.6 and 0.8 were studied experimentally. Using Neel, Gilleo and Dionne theories, the magnetic moments and Curie points were calculated respectively. It is shown that the experimental results were well in agreement with the Gilleo (Curie points) and Dionne (saturation moments) theories. The linearly incresing dependence of FMR line width with frequency (3.6-17 GHz) were discussed in terms of phenomenal theory. The occupancy of V5+ and In3+ ions in tetrahedral (d) and octahedral (a) sites were determined indirectly from the paramagnetic Mossbiuer spectroscopy.更多还原
