Superconductivity of Thin Film Intermetallic Compounds.
Abstract
Investigations of both macroscopic and microscopic properties of thin film superconducting materials have been carried out. Compounds under study prior to the discovery of high-Tc superconductors, were either technologically significant, or involved possible unique mechanisms for superconductivity whose realization might extend the range of critical parameters. These include low carrier density superconductors, selected Heavy Fermion Compounds, and Chevrel Phase superconductors. Among the low-carrier density systems were films of Lead Tellurium and mixtures of Lanthanium Sulfide. These were prepared with the idea of ultimately fabricating FET-like devices. Films of the Heavy Fermion Compounds UPt3 and UBe13 were prepared and the critical fields and proximity effects in the latter were studied. With the advent of the high-Tc materials the program shifted to their study and measurements of their time-dependent magnetization, XPS spectra, and tunneling spectra were carried out on both bulk and thin film materials.
