The
manipulation of two-dimensional (2D) ferromagnetic materials
by spin current is emerging as the central theme of 2D spintronics
research. A paradigm of spintronic devices, the spin Hall magnetoresistance
(SMR) device, has been elucidated to obtain direct evidence of spin
transfer torque (STT) on a three-dimensional (3D) ferromagnet. Here,
we present pioneering results on the SMR effect in a 2D cobalt-doped
MoS2/Ta van der Waals heterostructure, confirming the existence
of STT by the magnetic-field angle dependence of the resistance. Our
study on the STT of 2D ferromagnetic materials indicates the feasibility
of the realization of 2D spintronic devices.
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.
