High Field Superconductivity of Chervel Phase Compounds
Abstract
A brief description is given on the electronic structure of complex systems and the origin of their electronically driven phase transitions. The properties of the Chevrel phase compounds, particularly SnMo6S8 and EuMo6S8, are of great scientific and technological interest because of their unusual high magnetic field properties including the enhancement of the upper critical field H sub c2 observed when Eu is added to SnMo6S8. For example, up to an Eu concentration of 0.5, t sub c is hardly changed with the depression occurring abruptly only at high concentration. This behavior is contrary to observations on all other materials with the addition of a local magnetic moment and the theory of Abrikosov and Gor'kov.
