Ramesh Domain walls in multiferroics can exhibit intriguing behaviors that are significantly different from the bulk of the material. We investigate strong magnetoresistance in domain walls of the model multiferroic BiFeO 3 by probing ordered arrays of 109° domain walls with temperature- and magnetic-field-... [Phys. Rev.
