Abstract

Heat-capacity measurements and determinations of the superconducting transition temperature as a function of applied pressure up to 10 kbar have been made on a number of $α$ -phase uranium-molybdenum alloys. Small additions of molybdenum rapidly change the superconducting properties of the $α$ phase. The strong initial pressure dependence of $T_{c}$ for pure $α$ -U is destroyed, and bulk superconducting behavior at zero pressure develops.
