Description:
(abstract)Magnetoresistance (MR) oscillations serve as a hallmark of intrinsic quantum behavior, tradi- tionally only observed in conducting systems. Here we report the discovery of MR oscillations in an insulating system, the vertical junction graphene/CrPS4/graphene where CrPS4 being a two- dimensional (2D) A-type antiferromagnetic semiconductor. Systematic investigations of MR peaks under varying conditions, including magnetic field direction, temperature, voltage bias, and layer number, elucidate a correlation between MR oscillations and spin-canted states in CrPS4. Experi- mental data and analysis point out the important role of the in-gap electronic states in generating MR oscillations, although their precise origin needs further investigations. Our findings not only illuminate the unique electronic transport properties of CrPS4 but also underscore the potential of van der Waals magnets for exploring novel phenomena.
