The successful application of superconductivity to motors and other power system components depends on several factors. One of these involves characterization and minimization of the ac loss in the superconductor used for fabrication of the component

We have predicted the behavior of magnetic screening of N/I/S trilayers as a function of a single parameter W that parameterizes the discontinuity of the order parameter at the interface. We have compared these calculations with experimental measurem

It has long been known that oxygen doping, cation doping and strain all strongly influence the superconducting transition temperature, T/sub c/, of high temperature superconductors (HTS). These factors become especially important when thin films are

We present results of transport spin-polarization measurements derived using PCAR. Several systems are discussed with the focus primarily on oxides. The phenomenology of spin-polarization, details of the PCAR technique, and comparisons of the experim

A new method for determining the transport spin-polarization, point contact tunneling from a low temperature superconductor into a ferromagnet, is used to determine the spin polarization of various ferromagnetic thin films and crystals. The Andreev r

We present measurements of the transport spin polarization of ${\mathrm{Ni}}_{x}{\mathrm{Fe}}_{1\ensuremath{-}x}$ $(0l~xl~1)$ using the recently developed point-contact Andreev reflection technique, and compare them with our first-principles calculat

We study the kinetic inductance in thin superconducting/normal metal (S/N) bilayer films where the penetration depth is greater than the S thickness. Using the two-coil mutual inductance method, we show that it is possible to estimate the dependence

We have studied Andreev reflection in point contacts formed between several low T/sub c/ superconductors and various spin polarized normal metals. We have also developed a theoretical model for the phenomenon. There is good accordance between theory

We have deposited novel bilayer thin films of a ferromagnetic material and YBa/sub 2/Cu/sub 3/O/sub 7/ separated by a thin Au diffusion barrier to study the effects of a spin polarized nonequilibrium quasiparticle population on the superconducting or
