Fig. 3: Variation of magnetic parameters across the magnetic compensation temperature of GdIG.

a Temperature dependence of the effective exchange constant extracted from the fittings in Fig. 2. b Extracted resonant field \({H}_{r}\) of the two coupled modes as a function of temperature at f = 10 GHz. The solid and open symbols are obtained from experiments and fitting, respectively. c Temperature dependence of the enhanced damping induced by coherent spin pumping between the two hybrid modes.
