Temperature Dependence of Photothermally Modulated FMR Signals: Investigation of Magnetostatic Modes in Yttrium Iron Garnet Films
Conference paper
Abstract
Photothermally-modulated ferromagnetic resonance (PM-FMR) spectra of magnetostatic modes in yttrium iron garnet have been recorded in the temperature range from 120 K to 580 K. As the Curie temperature is approached, the conventional FMR signal becomes smaller, whereas, as expected from theory, the PM-FMR signal markedly grows. Based on the present result the theoretical description of the PM-FMR signal generation process has been improved.
