Negligible thermal contributions to the spin pumping signal in ferromagnetic metal–platinum bilayers”

Spin pumping by ferromagnetic resonance is one of the most common techniques to determine spin Hall angles, Edelstein lengths, or spin diffusion lengths of a large variety of materials. In recent years, there have been increasing concerns over the interpretation of these experiments, underlining that the signal could arise purely from thermoelectric effects rather than […]

Coherent generation and detection of acoustic phonons in topological nanocavities

Inspired by concepts developed for fermionic systems in the framework of condensed matter physics, topology and topological states are recently being explored also in bosonic systems. Recently, some of these concepts have been successfully applied to acoustic phonons in nanoscale multilayered systems. The reported demonstration of confined topological phononic modes was based on Raman scattering […]
