Abstract

The authors prepared Mo₆₀Re₄₀ thin films by single target magnetron sputtering. All the films analyzed exhibited a sharp superconductive transition and values of the critical temperature T_c up to 13 K were achieved. Structural analyses (EDS and X-rays) were performed on the samples. A15 phase was obtained even at low deposition temperatures. From the measured low temperature resistivity O_c and critical temperature T _c an estimate of the theoretical BCS surface resistance is inferred and compared with that of niobium
