摘要：

The effect of hydrostatic pressure on the superconductivity in LiFeAs is investigated up to 1.8GPa. The superconducting transition temperature, T-c, decreases linearly with pressure at a rate of 1.5K/GPa. The negative pressure coefficient of T-c and the high ambient pressure T-c indicate that LiFeAs is the high-pressure analogue of the isoelectronic SrFe2As2 and BaFe2As2. Copyright (C) EPLA, 2009
