Web21 mrt. 2024 · Spin-orbit torques (SOTs) have emerged recently as practical tools to control the magnetization in spintronic devices, but it is debated what the underlying fundamental processes are that enable fast and energy-efficient magnetization switching. Webwas solved about a decade ago bythe modern theoryof po-larization, based on a Berryphase.[1,2] A similar theoryfor the case of orbital magnetization is still lacking and is sorely needed. We present here the first step towards such a theory. The magnetization M of a condensed, macroscopicallyho-mogeneous, sample is an intensive ...
