Temporal and spatial attenuation of inertial spin waves driven by spin-transfer torques
Magnetic damping induces the temporal and spatial decay of spin waves,
characterized by the damping factor and attenuating length, both of which can
be measured to determine various magnetic and spin-transport parameters. By
investigating the dispersion and dissipation of inertial spin waves driven by
spin-transfer torques, we find that magnetic inertia modifies the dependence of
the damping factor and attenuating length on the electric current and spin wave
frequency. This provides a valuable method for probing the inertial relaxation
time.
