摘要:
Using theoretical expressions for the magnetization curve of polycrystalline ferrimagnets given previously, we have considered the effect of a grain size distribution on the magnetization versus applied magnetic field curve. We have observed the effects of various theoretical probability distribution functions and compared them with an experimental curve of yttrium iron garnet, Y3Fe5O12. The best fitting was obtained with a normal logarithmic distribution function for the grain size distribution of the sample.
