Magnetic relaxation in bilayers of yttrium iron garnet/platinum due to the dynamic coupling at the interface
S. M. Rezende, R. Rodríguez-Suárez, M. M. Soares +2
We show that in ferromagnetic (FM)/normal metal (NM) bilayers the dynamic coupling at the interface transfers an additional magnetic relaxation from the heavily damped motion of th…

Spin Seebeck Effect: Amplification of Spin Waves by Thermal Torque
E. Padrón-Hernández, A. Azevedo, S. M. Rezende
We observe amplification of spin-wave packets propagating along a film of yttrium iron garnet (YIG) subject to a transverse temperature gradient. The amplification is attributed to…
