Abstract : The current carrying capacity of double layer films consisting of two different superconductors was studied. After aging (which probably entails the formation of intermetallic compounds), an intermediate zone displayed 'hard superconductor' behavior. It was for the first time demonstrated that a magnetic field perpendicular to a superconducting film penetrates the film spotwise, each spot containing one quantum of magnetic flux. This effect was studied with alloy films of varying composition to determine how the Ginzburg-Iandau parameter of the superconductor changes with temperature. This parameter roughly indicates the 'hardness' of a superconductor and thus its technical usefulness. The thermal conductivity of films was studied to clarify the behavior of the electronic system as a function of temperature and of the magnetic field. (Author)
