Abstract
The frequency behavior of polycrystalline ferrites with composition Zn 0.64Ni0.36Fe2O4 was investigated in the 100 Hz to 13 MHz frequency and 300-900 K temperature ranges. A comparison of the thermal behavior of the domain wall relaxation frequency with the magnetocrystalline anis otropy constant exhibited a linear relationship. These results are int erpreted in terms of the restoring force factor for wall bulging. We e xplore the possibility of using frequency measurements to investigate the anisotropy constant in polycrystalline samples.
