Query: Magnetic Proximity Effect in 2D Ferromagnetic CrBr3/Graphene van der
  Waals Heterostructures   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, we
report the investigation of magnetic proximity effect in 2D CrBr3/graphene van
der Waals heterostructures, which is probed by Zeeman spin Hall effect through
non-local measurements. Zeeman splitting field estimation 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 at {\nu} = 0 may attribute
to the MPE induced new ground state phases. This MPE revealed in our
CrBr3/graphene van der Waals heterostructures therefore provides a solid
physics basis and key functionality for next generation 2D spin logic and
memory devices.
