Description
Ferrimagnetic resonance experiments were carried out on polycrystalline nickel cadmium ferrite (Ni_<0・7>Cd_<0・3>Fe_2O_4) in the temperature range from -180℃ to 100℃ at 9500MC and 24000MC in order to investigate the temperature dependence of the line width ⊿H and the g-value.
The writer used a standard electron spin resonace equipment at 9500MC, because of the high fidelity in measurements. As a result, it was clarified that the line width ⊿H is affected to a great extent by both the temperature and the frequency, in such a way that it increases with decreasing temperature and with increasing frequency. The measured line width was 400 oersted at -180℃ and 140 oersted at 100℃, showing a tendency to increase markedly with decreasing temperature below 0℃. The g-value was 2.13 at -180℃ and 2.03 at 100℃, gradually increasing with decreasing temperature. It was further known that the resonance field and the line width were remarkably affected by a slight deviation of the sample shape from sphericity.
