| Abstract: | A recent theoretical calculation by Papaconstantopoulos predicted superconductivity in platinum hydride, possibly with a rather high critical temperature (about 10 K as in PdH). We have produced PtHx (x ? 4.00) by ion-implantation, and find no evidence for superconductivity above 1.7 K. Residual resistivity measurements indicate that (in contrast to previous results on NiHx and PdHx) the Pt monohydride is not formed. We have considered the possibility that the dihydride might be formed. |
