Dynamic Critical Phenomena of the Superconducting Transition
One of the reasons why the Monte Carlo results do not accurately reproduce the dynamic exponent of the system is that a key assumption is found not to hold true. Equating Monte Carlo time to real time is believed to reproduce relaxational dynamics, but this is found not to be the case for the …

Effects of silicon monoxide overlays on the normal to superconducting transition time in thin indium films
This thesis investigates the normal to superconducting transition time (hereafter called the backswitch time) in thin films of indium. Varying thicknesses of silicon monoxide have been evaporated over the indium films and the effect of these layers has been observed at different temperatures over a …

The effect of manganese doping on the superconducting transition temperature and the upper critical field of tin-molybdenum-sulfide
We have measured the superconducting transition temperature, Tc' and the upper critical field, Hc2 (T), of manganese-doped SnMo6S8 (MnxSn1_xMo6S8)' These samples had reproducible superconducting properties. They were characterized by x-ray powder diffractometry, optical microscopy. electron …

Temperature dependence of impurity resonances in cuprate superconductors
In conventional superconductors the superconducting gap in the electronic excitation spectrum prevents scattering of low energy electrons. In high temperature superconductors (HTS) an additional gap, the pseudogap, develops well above the superconducting transition temperature Tc. The identity of …
