Domain Structures in Superconductors

Synopsis
Shows the intermediate-state structures of an evaporated superconducting lead film of 7mm thickness in a vertically applied magnetic field of variable amplitude. The domains have been made visible by means of the Faraday effect in thin evaporated EuS/EuF2 films. Shows the following: 1) The penetration of magnetic flux, the formation of normal meanders and of normal honeycomb-like cells upon increasing the magnetic field amplitude; 2) The nucleation of superconducting filaments, the formation of superconducting meanders and normal domains issuing from the sample on decreasing the magnetic-field amplitude. 3) The growth, the shrinkage and the disappearance of superconducting filaments upon slowly oscillating the magnetic field amplitude. An Encyclopaedia Cinematographica film.
