Superconductivity and structural phase transition in BaBi<sub>3</sub> under pressure

ORAL

Abstract

Inspired by recent investigations of superconductivity in single crystal BaBi3 [1] we performed a comprehensive pressure study of low field magnetization and electrical resistivity in zero and applied field in single crystals of this compound, combined with first principles calculations. The results suggest that BaBi3 undergoes a pressure-induced structural transition, possibly from a lower pressure (below 1 GPa) tetragonal phase to a higher pressure cubic phase, with the latter being a host for superconductivity with higher Tc.
