Abstract
Au/Pr0.5Ca0.5MnO3-y (PCMO)/YBa2Cu3O7-z(YBCO) sandwich-type junctions were f abricated on MgO (001) substrates, and their resistivity was measured with a constant voltage applied between the top Au and bottom YBCO layers. In th e low-temperature region, the resistivity was drastically suppressed for se veral orders with only a few volts applied due to field-induced switching e ffect of PCMO. When the voltage was removed from the junctions in a low-res istivity state, two types of behavior were observed: one which recovers to a high-resistivity state and another which does not.
