自从35年前在35 K的高温下发现超导以来，高压实验在铜氧化物超导性的发展中起到了至关重要的作用。发现后不久，压缩实验揭示了一个大的/，激发了对材料中“化学压力”的研究，导致了90 K超导体。随后发现的铜酸盐超导体表现出从30 K到140 K的范围，包括通常研究的Bi，Tl和Hg基家族。压力对这些材料的超导电性有很大的影响，包括在30 GPa下Hg基铜酸盐从140 K升高到166 K。回顾过去的实验表明，压力掺杂孔进入所有铜酸盐共同的平面。对这些材料进一步详细的高压研究应该加深我们对铜酸盐超导性的理解，以及在铜酸盐中达到更高超导性的可能性。
ABSTRACT Since the discovery of high temperature superconductivity in at an unprecedented of 35 K over 35 years ago, high pressure experiments have played a critical role in bdeveloping cuprate superconductivity. Soon after its discovery, compression experiments on revealed a large / , motivating the study of ‘chemical pressure’ in the material that led to the 90 K Superconductor . Cuprate superconductors discovered subsequently exhibited a range of from 30 K to 140 K, including the commonly studied Bi, Tl, and Hg based families. Pressure has large effects on superconductivity in these materials, including raising in the Hg based cuprates from 140 K to 166 K at 30 GPa. Reviewing past experiments indicate that pressure dopes holes into the planes common to all cuprates. Further detailed high pressure studies of these materials should deepen our understanding of cuprate superconductivity and the possibility of reaching still higher in cuprates.
