ABSTRACT
On the basis of exact solutions to the London equation, the magnetic moment of a type II superconductor filament surrounded by a soft-magnet environment is calculated and the procedure of extracting the superconductor contribution from magnetic measurements is suggested. A comparison of theoretical results with experiments on MgB2/Fe wires allows the estimation of the value of critical current for the first magnetic flux penetration.

    Electrical transport measurements were performed on single electrodeposited superconducting lead nanowires (330 nm diameter) by applying a magnetic field parallel to the wire axis. We observe a vortex penetration while the nanowire is in the dissipative state generated by a phase-slip center....
