Popis:	Fe 100− x Zr x amorphous alloys are shown to be superconducting for x ⪸ 68 ± 2 . Comparison of low temperature specific heat measurements for FeZr with previous results for NiZr and CuZr show that the composition trends of N 0 ( E F ) are consistent with recent theoretical models and photoemission results. Furthermore, the factor η = N 0 ( E F )〈 I 2 〉 is composition independent and the same for all superconductors in these three alloy series. From these results we conclude that T c of pure amorphous Zr will be 5.1 K, compared with 0.55 K for crystalline Zr.
