Bulk Superconductivity in Dilute Hexagonal Titanium Alloys

Abstract
The superconductivity, the low-temperature specific heat, and the paramagnetic susceptibility have been investigated in a series of dilute hexagonal titanium alloys. In the solid solutions with V or Nb, both the transition temperature and the density of states are strongly increased and the entire volume exhibits superconductivity. A similar study of Ti-Fe alloys suggests either an incomplete volume transition or a different entropy variation in the superconducting state.
