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.
