Abstract

We present the results of investigations of the temperature dependences of complex conductivity σ(T) = σ ′(T)−i σ ″(T) at frequency 9.4 GHz in series of single crystals V3+x Si1−x with different Si content. The data exhibit peculiarities typical for multiband superconductors, namely a nonlinear temperature dependence of resistivity above superconducting transition temperature T c , suppression of superconducting transition temperature T c by nonmagnetic impurities, a positive curvature of σ ″(T) curves close to T c , and a coherence peak in σ ′(T) at T∼T c /2. Using a two-band model in the weak-coupling regime, we demonstrate that the behavior of T c and the evolution of σ(T) with Si-content variation are consistently described by changing of the interband scattering rate.
