We report on microwave measurements of hybrid superconductor-ferromagnet-superconductor (SFF’S’) junctions with a composite oxide ferromagnetic bilayer with non-collinear magnetizations. Current-phase relation (CPR) of the junction superconducting current has been evaluated as a function of magnetic field. A significant part of the 2nd harmonic in CPR, about 50%, was measured.

Nb / Au / YBa 2 Cu 3 O x heterojunctions in (001) and (1 1 20)-oriented YBa 2 Cu 3 O x films have been fabricated. I-V curves of both kinds of heterojunctions show pronounced superconducting current. As affected by microwave radiation Shapiro steps at voltages hf/ 4e arise in the I-V curves of Nb / Au / YBa 2 Cu 3 O x (001) heterojunctions implying the double periodic (~ sin 2φ) superconducting current-phase relation. However, in the case of Nb / Au / YBa 2 Cu 3 O x (1 1 20) heterojunctions Shapiro steps have been observed in the I-V curves at voltages hf/ 2e only supporting a sinusoidal (~ sin φ) superconducting current-phase relation within measurement accuracy. A zero bias conductance peak associated with zero-energy Andreev bound states occurs in the I-V curve of the Nb / Au / YBa 2 Cu 3 O x (1 1 20) heterojunctions. We discuss the experimental results in terms of the d-wave symmetrical superconducting order parameter in YBCO.
