Zusammenfassung

We present a detailed analysis of the dependence of the critical current Ic on an in-plane magnetic field B of 0, π, and 0−π superconductor-insulator-ferromagnet-superconductor Josephson junctions. Ic(B) of the 0 and the π junction closely follows a Fraunhofer pattern, indicating a homogeneous critical current density jc(x). The maximum of Ic(B) is slightly shifted along the field axis, pointing to a small remanent in-plane magnetization of the F-layer along the field axis. Ic(B) of the 0−π junction exhibits the characteristic central minimum. Ic, however, has a finite value here, due to an asymmetry of jc in the 0 and the π part. In addition, this Ic(B) exhibits asymmetric maxima and bumped minima. To explain these features in detail, flux penetration being different in the 0 part and the π part needs to be taken into account. We discuss this asymmetry in relation to the magnetic properties of the F-layer and the fabrication technique used to produce the 0−π junctions.
