Magnetic flux behavior in flat type II superconductors in external perpendicular field has some peculiarities determined only by their shape. The most important one is a barrier-like initial flux penetration into such thin samples with rectangular cross-sections. Another one is a rather peculiar flu

Magnetostriction loops of a hard superconductor are calculated analytically. The geometry under consideration is a thin flat superconductor in a magnetic field perpendicular to the flat face of the sample. The analytical representation of the results is given in a relationship with the magnetic flux
It is shown, within a simple model calculation, that the critical current density of an S/N/S junction in a high paralel magnetic field decays exponentially. The comparison of the theoretical results with experimental data for the Pb/Cd/Pb junction and YBCO films is given.
The magnetization of a V3Ga superconducting tape between two successive flux jumps has been experimentally determined by means of search coil measurement in an increasing field perpendicular to the surface. On the basis of these experimental results, an attempt is made to determine theoretically the
A new method of investigating the relationship between current density and the magnetic induction in Type II superconductors has revealed both microscopic and fairly long range variations, apparently arising from inhomogeneities in the samples. The method also permits direct observation of field dis
