Alternating current Hanle effect as poor man's paramagnetic resonance
arXiv:2406.13886 · doi:10.1103/PhysRevB.109.224427
Abstract
It is shown that in spin injection experiments the interplay between external magnetic field and alternating current can be observed already on a single ferromagnet/normal metal interface. The interface resistance is predicted to exhibit prominent features whenever the frequency of spin precession in the applied field becomes equal to the frequency of the driving current. Using these features, material-specific g-factors of electrons in normal metals can be measured with less effort, albeit also with less precision.
