Query: Impact of hydrostatic pressure on superconductivity of Sr0.5La0.5FBiS2   We report the impact of hydrostatic pressure (0-1.97GPa) on superconductivity
of recently discovered 2K superconductor Sr0.5La0.5FBiS2. Resistivity under
pressure measurements are performed by using HPC-33 Piston type pressure cell
with Quantum design DC resistivity Option. The superconducting transition
temperature (Tc) is increased by 5 fold to around 10K with just above 1GPa
pressure, which remains nearly unaltered for studied higher pressures of up to
1.97GPa. The fivefold increase in Tc of Sr0.5La0.5FBiS2 with just above 1GPa
pressure suggests very strong electron correlations in these systems and the
same calls for the attention of solid state physics community.
