Physical properties of single crystalline BaSn₅

Abstract

We present a comprehensive study of the binary intermetallic superconductor, BaSn₅. High-quality single crystalline BaSn₅ was grown out of a Sn flux. Detailed thermodynamic and transport measurements were performed to study BaSn₅'s normal and superconducting state properties. This material appears to be a strongly coupled, multiband superconductor. H _c2(T) is almost isotropic. De Haas–van Alphen oscillations were observed and two effective masses were estimated from the FFT spectra. Hydrostatic pressure causes a decrease in the superconducting transition temperature at the rate of ≈−0.053 ± 0.001 K/kbar.
