DOI: 10.1002/adma.202105023
Abstract: We provide evidence of robust spin-dependent transport in monolayer graphene, deposited on the (0001) surface of the antiferromagnetic (AFM)/magneto-electric oxide chromia (Cr2 O3 ). Measurements performed in the non-local spin-Hall geometry reveal a robust signal… read more here.
