Abstract
The numerical solutions of the Landau-Lifshitz equation and magnetization signals derived from them have been analyzed for the purpose of investigating the nature of the effect of delayed acceleration of the transient process experimentally observed in ferrite-garnet films with in-plane anisotropy in 90° pulsed magnetization. The results of the analysis performed have been compared with the experimental data. It has been found that the presence of biaxial anisotropy in the plane of real ferrite-garnet films is primarily responsible for the effect under investigation, as well as for the weak dependence of the intensity of magnetization oscillations occurring during the magnetization on the magnetizing pulse front duration. Analysis of the transverse signals has demonstrated that the Landau-Lifshitz damping constant λ, which takes into account the energy loss in the Landau-Lifshitz equation, in real ferrite-garnet films strongly depends on the angle φ of rotation of the magnetization.
