Superconductivity of Thin Film Intermetallic Compounds.
Abstract
The macroscopic as well as microscopic properties of selected thin film superconducting compounds are being investigated. The materials being studied are either members of technologically significant systems or involve possible unique mechanisms for superconductivity whose realization should extend the range of critical parameters to either higher temperatures of higher critical fields. Materials under study are the superconducting Cheverel phase compounds, selected Heavy Fermion compounds and a low carrier density superconductor, T1 doped PbTe. The latter is being investigated with an idea to understanding the superconducting field effect. Processing of the Chevrel Phase compounds is carried out in a multi-source deposition system. The latter has been upgraded and improved during the grant period. The electrical and magnetic properties of the reentrant superconductor HoMo6S8 have been investigated in some detail with the magnetic and superconducting character of the low-temperature phase found to be dependent on the degree of disorder in the film. Single crystal films of the Heavy Fermion compound UPt3 have been prepared. Although these films are highly ordered they have not been found to be superconducting, perhaps because they are off stoichiometry by as little as one percent.
