Abstract:We experimentally investigate the influence of the pressure on the spin-charge conversion efficiency in a CoFeB/Pt bilayer system by using a specially designed pressure-cell setup. The dc voltage spectra under the dynamical spin injection is found to show the systematic increase with increasing the pressure. These modifications can be understood by the enhancement of the spin-charge conversion efficiency due to the modulation of the spin-orbit interaction and/or the interface transparency. The present dem… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
