Abstract
Metallic conductivity and superconductivity (SC) in the title compound is only observed under hydrostatic pressure. The critical pressure fo r the occurrence of SC (P-crit = 290 bar for x=0) is lowered with incr easing Br-content In a pressure range above this pressure, whose width seems to depend on sample quality, reentrant SC is observed, presumab ly due to a competition with a magnetic ground state. We show by means of DC diamagnetic measurements, that the reentrant SC is a volume pro perty and that the reentrant transition is a first order transition fr om a SC to a magnetically ordered state.
