Abstract
- Using ferromagnetic La<subscript>0.67</subscript>Sr<subscript>0.33</subscript>MnO<subscript>3</subscript> electrodes bridged by single-layer graphene, we observe magnetoresistive changes of ~32-35 MΩ at 5 K. Magneto-optical Kerr effect microscopy at the same temperature reveals that the magnetoresistance arises from in-plane reorientations of electrode magnetization, evidencing tunnelling anisotropic magnetoresistance at the La<subscript>0.67</subscript>Sr<subscript>0.33</subscript>MnO<subscript>3</subscript>-graphene interfaces. Large resistance switching without spin transport through the non-magnetic channel could be attractive for graphene-based magnetic-sensing applications. [ABSTRACT FROM AUTHOR]
