Abstract

A study of electron-phonon coupling in pure Mg by means of proximity tunneling into Mg films backed by recrystallized Nb foils is reported. The results indicate that Mg in thicknesses of 20-100 Å continuously covers a clean Nb surface and yield a value λ=0.29±0.03 for the electron-phonon coupling constant. This is consistent with an as yet unobserved superconducting T_c=0.3 mK for pure Mg.
