The periodic ___domain pattern of BiFeO3 enables the anisotropic superconductivity in YBa2Cu3O7 − x. In this work, we introduce a design of periodic multiferroic ___domain patterns to create the anisotropic superconductivity. High TC can be found when we measured the resistance parallel to the ___domain wall direction and the broader transition with lower TC is found to be perpendicular to the ___domain walls. (a) and (b) the resistance versus temperature in YBa2Cu3O7 − x/BiFeO3 heterostructures with two different ___domain patterns 109° and 71°, respectively.
