摘要：

Superconductivity of barium is observed under high volume compression. The high-pressure phase, Ba II, has a Tc somewhat lower than 1.3°K at 55 kbar, Tc sharply rising with increase of pressure. A second solid phase above 140 kbar has a Tc of approximately 5°K. © 1969 The American Physical Society.
