Query: Antisymmetric magnetoresistance in van der Waals
  Fe3GeTe2/graphite/Fe3GeTe2 tri-layer heterostructures   Van der Waals (vdW) ferromagnetic materials are rapidly establishing
themselves as effective building blocks for next generation spintronic devices.
When layered with non-magnetic vdW materials, such as graphene and/or
topological insulators, vdW heterostructures can be assembled (with no
requirement for lattice matching) to provide otherwise unattainable device
structures and functionalities. We report a hitherto rarely seen antisymmetric
magnetoresistance (MR) effect in van der Waals heterostructured
Fe3GeTe2/graphite/Fe3GeTe2 devices. Unlike conventional giant magnetoresistance
(GMR) which is characterized by two resistance states, the MR in these vdW
heterostructures features distinct high, intermediate and low resistance
states. This unique characteristic is suggestive of underlying physical
mechanisms that differ from those observed before. After theoretical
calculations, the three resistance behavior was attributed to a spin momentum
locking induced spin polarized current at the graphite/FGT interface. Our work
reveals that ferromagnetic heterostructures assembled from vdW materials can
exhibit substantially different properties to those exhibited by similar
heterostructures grown in vacuum. Hence, it highlights the potential for new
physics and new spintronic applications to be discovered using vdW
heterostructures.
