We have measured magnetic diffraction patterns of critical currents of vertical geometry YBa2Cu3O7−x(YBCO)/Ag/PbIn Josephson junctions made with in-plane aligned a-axis oriented YBCO films. Anisotropic penetration depths in YBCO and the resulting Josephson penetration depths give rise to diffraction patterns which are distinctly different when the magnetic field is applied in two orthogonal directions (b and c). The London penetration depths of YBCO, λb, and λc, are found to be ∼2000 A(ring) and ∼1.2 μm, respectively, at 4.2 K. Intrinsic IcRn products of up to 0.2 mV have been obtained in these junctions. © 1996 American Institute of Physics.
