Electron-phonon interaction in hydrostatically compressed indium–tin alloys

The superconducting characteristics and electron-phonon interaction parameters of indium-tin alloys under pressure of up to 10 kbar were studied by the method of single-particle electron tunneling. A close correlation between the interaction constant λ. and the ratio of superconductivity parameters 2Δ0/TK as well as its derivative with respect to pressure has been established in these materials with the same crystallographic structure and phonon spectrum.
