THE PROPERTIES OF SUPERCONDUCTING MO-RE ALLOYS.
Abstract
This report gives details of the research carried out and the results obtained therefrom during this contract on the low temperature properties of Mo-Re alloys in the superconducting and normal states. Measurements were made on a variety of Mo-Re alloys in various states of anneal, the alloys being in the form of fine wires, as suitable for the winding of high-field superconducting solenoids. Micrograph studies were made to determine the percentage of the various phases present in each specimen. The low temperature measurements covered observations on the various specimens of (1) the electrical resistivity as a function of temperature and of magnetic field, (2) the magnetic moment as a function of temperature and magnetic field and (3) the thermal conductivity also as a function of temperature and magnetic field. The measurements yielded evaluations of the three critical magnetic fields, HsubC1, HsubC2, and Hsub3 as a function of temperature and alloy constitution, the transition temperatures TsubC and the Landau-Ginsburg parameters k. Detailed comparisons of the results are made with theoretical predictions and with results by previous authors on similar high-field superconducting alloys. (Author)
