摘要

We report the ac magnetic susceptibility, electrical resistance, and x-ray diffraction measurements of PtHx, (x similar or equal to 1) in diamond anvil cells, that reveal the superconducting transition. At 30 GPa, when PtHx, is in a P6(3)/mmc structure, PtHx, exhibits the superconducting transition at 7 K. Remarkably, the observed T-c is higher than that of powdered Pt by more than three orders of magnitude. It is suggested that the noble metals in the periodic table of elements possibly form a region where hydrides have higher T-c than elements.
