Abstract

Josephson coupling between an s- and d-wave superconductor through a 50 nm thick Ca1�xSrxCuO2 antiferromagnetic layer was observed for the hybrid Nb=Au=Ca1�xSrxCuO2=YBa2Cu3O7�� heterostructures and investigated as a function of temperature, magnetic field, and applied millimeter-wave electromagnetic radiation. The magnetic field dependence of the supercurrent Ic�H� exhibits anomalously rapid oscillations, which is the first experimental evidence of the theoretically predicted giant magnetooscillations in Josephson junctions with antiferromagnetic interlayers.
