Dynamics of the Magnetization Vector during the 180° Pulsed Magnetization Reversal of Ferrite–Garnet Films with Complex Anisotropy
The regime of 180° pulsed magnetization reversal of ferrite-garnet films with planar anisotropy in the region of external fields, in which the mechanism of uniform rotation of the magnetization operates, is investigated for the first time. An analysis of numerical solutions of the Landau–Lifshitz equation and our experimental studies show that, as in the case of the 90° pulsed magnetization, the presence of biaxial anisotropy in real ferrite–garnet films also leads to the so-called “effect of delayed acceleration of the transient process.” In addition, it is found that under certain conditions it is possible to achieve two stable final positions of the magnetization vector that correspond to 180° and 90°.
