We have succeeded in growing Pr x Os 4 Sb 12 single crystals under $4 GPa with high Pr-site filling fraction x. The electrical resistance measurements clearly show that the superconducting (SC) transition is sharper and the onset temperatures is lower in the single crystal samples grown under high p

We performed synchrotron X-ray powder diffraction experiments on the filled skutterudite PrRu 4 P 12 at high pressure and low temperature to investigate the role of structural changes in the metallization and superconducting transition above 11 GPa. We compared the structural parameters between the
