Theoretical investigation of the relationships between magnetic circular dichroism signals and Gilbert damping coefficient in magnetic films

Inspired by the traditional ferromagnetic resonance (FMR) approach, the relationships between two kinds of magnetic circular dichroism signals and the Gilbert damping coefficient in magnetic films are theoretically investigated within linear response framework. These results may provide inspirations on potential experimental strategies to remeasure the Gilbert damping coefficient, which is traditionally obtained from FMR technique.
