Fig. 7. Temperature dependence on magnetization precession in YIG:Co.

a Time-resolved magnetization precession at zero magnetic field. Inset shows the magnetization precession at 300 K with a color code used in the 3D map in Fig. 2d. The precession traces show the out-of-plane magnetization component dynamics stimulated by the pump pulse with polarization E || [100] and fluence of 10 mJ/cm² in the pump and probe geometry. b Temperature dependence of the normalized amplitude of the photoinduced magnetization precession which is extracted from time-resolved Faraday rotation. c The results of the calculation of effective anisotropy field $H_A$ as a function of frequency f using the Kittel formula²⁶.
