Abstract

As discussed in previous chapters, the precessional magnetization dynamics is described by Landau–Lifshitz–Gilbert equation. It may be noticed from the LLG equation that four important material parameters, namely, Landé g-factor, saturation magnetization, magnetic anisotropy, and Gilbert damping parameters directly govern the precessional dynamics. Ultrafast demagnetization and relaxation phenomena are also influenced by material parameters and sample conditions. To understand deeply, various factors related to material aspects of the specimen which affect the dynamics, numerous interesting theoretical and experimental studies have been performed.
