A PREVIOUS paper I it was reported that in wires of type II superconductors strong additional damping of torsional oscillations is observed in the range He1 < H< He2 which is caused by the pinning of Abrikosov flux lines on inhomogeneities of the crystal lattice. The present paper describes pinning

The appropriate magnetic and thermal diffusion equations for magnetization of a "hard" type II superconductor have been solved numerically using a digital computer, and show the initiation of flux jumps at applied field strengths in agreement with experimentally observed magnitudes.
In the concentric arrangement of a superconducting tube and a high-conductivity aluminium cylinder, the magnetic flux variation arising from flux jumps occurred only within the superconducting tube itself, whereas the magnetic flux in the normal metal was almost completely frozen during the flux jum
This paper reports the experimental investigations into two different methods of reducing flux creep and magnetic relaxation in high T c YBa2Cu307 and low T c Nb-Ti. For temperatures T \_< 4.2 K temperature reduction leads to a considerable reduction of the flux creep rate. The second method for red
