摘要：

A transition of Ce impurities from a magnetic to a nonmagnetic state has been observed in superconducting La: Ce alloys at high pressure. The critical pressure for maximum pair breaking in La: Ce alloys is lower for the fcc than for the dhcp phase. The highest transition temperature of an elemental superconductor (12°K) is reported for pure La at 140 kbar. © 1969 The American Physical Society.
