Current-phase relation of superconductor-ferromagnet-superconductor junctions with a composite interlayer
Paper in proceeding, 2015
We report on microwave measurements of hybrid superconductor-ferromagnetsuperconductor (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 2 nd harmonic in CPR, about 50%, was measured.
