Description
The bcc phase of barium is a superconductor. T/sub c/ increases steeply with pressure from 0.06 K at 37 kbar to 0.5 K at 48 kbar. A fit of McMillan's expression for T/sub c/ suggests a T/sub c/ already in the millikelvin range at 30 kbar. Phonon softening as inferred from the decreasing melting curve is insufficient to account for the rise of T/sub c/ with pressure
