Effect of pressure on the physical properties of the superconductor NiBi3

Abstract

We present an experimental study of the superconducting properties of NiBi3 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 Tc from ~ 4.1K to ~ 3K by pressures up to 2GPa. By taking into account the change of the band structure as a function of pressure, we argue that the decrease in Tc is consistent with conventional, electron-phonon-mediated BCS-type superconductivity.
