Unidirectional orbital magnetoresistance in light-metal–ferromagnet bilayers
Shilei Ding, Paul Noël, Gunasheel Kauwtilyaa Krishnaswamy, Pietro Gambardella
Abstract
An electric current flowing in a semioxidized Cu layer induces a transverse flow of orbital angular momentum into an adjacent ferromagnetic layer. A nonreciprocal magnetoresistance emerges, which arises from the interaction of the orbital current and magnetization and that changes signs upon reversal of either.
