摘要：

The temperature-dependent ac susceptibility of the filled skutterudite superconductor PrPt4Ge12 has been measured under hydrostatic He-gas pressure to 0.58 GPa. The superconducting transition temperature T-c decreases linearly with pressure P from 7.91 K at ambient pressure to 7.83 K at 0.58 GPa, giving the rate dT(c)/dP = -0.19 +/- 0.03 K/GPa. Evidence is presented that suggests that the value of T-c in this compound is slightly reduced due to magnetic pair-breaking effects from the Pr3+ cations. (C) 2012 Elsevier B. V.
