摘要：

The effect of hydrostatic pressure up to 15 kbar on the superconducting transition temperature T(c) is reported for five compounds in the quaternary system RENi2B2C (RE=Y, Lu, Tm, Er, Ho). The compounds with RE=Y, Lu, Tm, Er display a modest linear variation of T(c) with pressure. The value of dT(c)/dp is ranging from -1.78 x 10(-5) K/bar up to + 1.88 x 10(-5) K/bar. In contrast, for HoNi2B2C some kind of interplay between long-range magnetic order and superconductivity occurs, which is strongly modified under applied pressure.
