摘要：

Resistive measurements in a cryogenic diamond anvil cell show that the Tc of YBa2Cu4O8 can be increased by almost 30 K by applying a pressure of 12 GPa. The pressure derivative is, however, not constant. At p {precedes above almost equal to} 5 GPa, dTc/dp≊ 5 K/GPa. At higher pressures dTc/dp decreases gradually and Tc saturates at ≈ 108 K. This behaviour is reproduced by a phenomenological model where Tc depends only on the number of holes in the CuO2 planes. © 1990.
