Abstract:
First investigated the mode 180° pulse the magnetization reversal of the films of ferrites-garnets with in-plane anisotropy in the external fields, which operates the mechanism of the homogeneous rotation of magnetization. Analysis of numerical solutions to the equations of Landau-Lifshitz, and we conducted experimental studies have shown that, as in the case of 90° pulse magnetization, the presence of real garnet ferrite film biaxial anisotropy also leads to the so-called "effect of delayed acceleration of the transition process." In addition, it is revealed that under certain conditions it is possible to achieve two stable end positions of the magnetization vector corresponding to the 180° and 90°.
