Static magnetization measurements under pressure indicate that the linear increase in Tc is initially rapid (dTc/dP ∼ 9.9 K · GPa-1) but slows down to dTc/dP ∼ 2.5 K · GPa-1 for P 0.18 GPa. The Tc of the superconducting phase is 32 K at pressure P 0.96 GPa. The simple rigid band model or the Bardeen, Cooper, Schrieffer theory may not be sufficient to account for our observations, if one assumes that the lattice parameters would be linearly decreased with pressure. © 2013 AIP Publishing LLC. |
