Abstract: Two-dimensional (2D) van der Waals heterostructures serve as a promising platform to exploit various physical phenomena in a diverse range of novel spintronic device applications. The efficient spin injection is the prerequisite for these devices. The recent discovery of magnetic 2D materials leads to the possibility of fully 2D van der Waals spintronics devices by implementing spin injection through magnetic proximity effect (MPE). Here, the investigation of magnetic proximity effect in 2D graphene/CrBr3 van der Waals heterostructures is reported, which is probed by Zeeman spin Hall effect through non-local measurements. Quantitative estimation of Zeeman splitting field demonstrates a significant magnetic proximity exchange field even in a low magnetic field. Furthermore, the observed anomalous longitudinal resistance changes at the Dirac point R_(XX,D) with increasing magnetic field near ν= 0 may attribute to the MPE induced new ground state phases. This MPE revealed in our graphene/CrBr3 van der Waals heterostructures therefore provides a solid physics basis and key functionality for next generation 2D spin logic and memory devices.
