Sputtered Nb3Ge films are doped with hydrogen by exposing them to acid and the effects of this hydrogen are studied. The hydrogen content of these films is measured using the15N nuclear resonance profiling method. Hydrogen incorporated at concentrations up to 1.8×1022cm−3(23 at.%) expands the lattice up to 2.5% and depresses the superconducting transition temperatureTc, ∼1 K per 1021H atoms/cm3. Hydrogen is also found in as‐sputtered films, the amount increasing as the film deposition temperature is reduced.
