Second sound is a quantum mechanical effect manifesting itself as a wave-like (in contrast with diffusion) heat transfer, or energy propagation, in a gas of quasi-particles. So far, this phenomenon has been observed only in an equilibrium gas of phon

Relation between unidirectional spin Hall magnetoresistance and spin current-driven magnon generation

Autor: Sergei Urazhdin, A. B. Rinkevich, Sergej O. Demokritov, Igor V. Borisenko, Vladislav E. Demidov

We perform electronic measurements of unidirectional spin Hall magnetoresistance (USMR) in a Permalloy/Pt bilayer, in conjunction with magneto-optical Brillouin light spectroscopy of spin current-driven magnon population. We show that the current dep

Publikováno v: Physical Review B. 96

We show that the sensitivity and depth selectivity of neutron reflectometry can be greatly enhanced through a waveguide design that takes advantage of the spin-dependent magnetic neutron scattering potential to steer spin-up and spin-down neutrons in
