Title: Effect of pressure on the physical properties of the superconductor NiBi 3

Abstract

Here, we present an experimental study of the superconducting properties of NiBi 3 as a function of pressure by means of resistivity and magnetization measurements and combine our results with DFT calculations of the band structure under pressure. We find a moderate suppression of the critical temperature T c from ~ 4.1 K to ~ 3 K by pressures up to 2 GPa. By taking into account the change of the band structure as a function of pressure, we argue that the decrease in T c is consistent with conventional, electron-phonon-mediated BCS-type superconductivity.
