| This work explores static magnetization distribution of planar ferrites. The effect of the shapes, the corners and the edges on the non-uniform distribution of the magnetization and the internal magnetic field has been numerically explored with the finite difference method. The magnetic interactions and effect inside the material, such as demagnetizing, exchange and external field as well as anisotropy effect, have been included in the investigation. The second part of the research studies the switching process for the substituted yttrium iron garnet. The effect of defects has also been explored.*; *Part of the work has been published in the article “Non-uniform internal field in planar ferrite elements” and has been published on IEEE. Trans. Mag., Vol. 37, No. 6, p3881 (2001). |
