Ferromagnetic resonance modulation in $$d$$-wave superconductor/ferromagnetic insulator bilayer systems

Ominato, Yuya*; Yamakage, Ai*; Kato, Takeo*; Matsuo, Mamoru

We investigate ferromagnetic resonance (FMR) modulation in $$d$$-wave superconductor (SC)/ferromagnetic insulator (FI) bilayer systems theoretically. The modulation of the Gilbert damping in these systems reflects the existence of nodes in the $$d$$-wave SC and shows power-law decay characteristics within the low-temperature and low-frequency limit. Our results indicate the effectiveness of the use of spin pumping as a probe technique to determine the symmetry of unconventional SCs with high sensitivity for nanoscale thin films.
