High-quality planar high-Tc Josephson junctions
Reproducible high-Tc Josephson junctions have been made in a rather simple two-step process using ion irradiation. A microbridge (1 to 5  µm wide) is firstly designed by ion irradiatin...

Interaction between the superconductor and ferromagnet in MgB2/Fe wires results in either a plateau or a peak effect in the field dependence of transport critical current, Ic(H). This is in addition to magnetic shielding of external field. Current theoretical models cannot account for the observed peak effect in Ic(H). This letter shows that the theoretical explanation of the peak effect should be sought in terms of interaction between superconductor and magnetic domain structure, obtained after the remagnetization of the iron sheath by the self-field of the current. There is a minimum value of critical current, below which the remagnetization of the iron sheath and peak effect in Ic(H) are not observed. ©2005 American Institute of Physics

  22. All of the current flows through superconducting core for I<Ic. However, for I>Ic, the current is expelled into the sheath, which results in a smaller self-field at the superconductor/iron interface
