Spin-orbit torque effects in all-electrical spin-wave spectroscopy experiments
José Solano Córdova, Jone Mencos, Richard Schlitz +10
Electrical excitation and detection of propagating spin waves are key elements of magnonic devices. While conventional antennas consisting of non-magnetic metals such as Au or Cu e…

Spin-polarization of the electric current in half-metallic CoMnSi Heusler thin films
José Solano Córdova, Anna Maria Friedel, Quentin Rossi +6
Using propagating spin wave spectroscopy we measure the spin wave Doppler shift in patterned MgO/CoMnSi/MgO thin films and determine the degree of spin-polarization of the elec…

Unraveling the temperature-dependent spin-polarized electron transport in iron via spin-wave Doppler shift
José Solano, Quentin Rossi, Jerome Robert +5
An electric current flowing in a ferromagnetic metal carries spin angular momentum, i.e. it is spin-polarized. Here, we measure the spin-wave Doppler shift induced by the transfer…
