High Temperature Resistive Phase Transition in A15 High Temperature Superconductors

  • Chapter
Superconductivity in d- and f-Band Metals

Abstract

Resistive measurements were made on A15 high temperature super-conductors. Anomalies indicative of a phase transition were observed at 433 K in a single crystal Nb3Sn and at 485 K in an unbacked Nb3Ge sputtered thin film. The results are compared with the high temperature transmission electron diffraction studies of Nb3Ge films by Schmidt et al. A discussion of a possible instability in the electron energy spectrum is made.
