Superconductivity of Cerium Under Pressure

Abstract

Superconductivity has been detected in a high-pressure phase of cerium at pressures higher than 50 kbar. This is the first example of a pure metal which, in different crystallographic phases, shows both magnetic ordering and superconductivity. The important question again arises whether the "collapsed" $\ensuremath{\alpha}$ phase will become superconducting at a certain pressure.
