Query: Pressure enhanced superconductivity at 10 K in La doped EuBiS2F   Polycrystalline Eu0.5La0.5BiS2F was synthesized by solid state reaction which
crystallizes in the tetragonal CeOBiS2 structure (P4/nmm). We report here
enhancement of Tc to 2.2 K in Eu0.5La0.5BiS2F (by electron doping in EuBiS2F
with Tc ~ 0.3 K). Eu0.5La0.5BiS2F is semiconducting down to 3 K and an onset of
superconductivity is seen at 2.2 K at ambient pressure. Upon application of
pressure the Tc could be enhanced upto 10 K. Step like features are seen in the
resistivity curves at intermediate pressures (0.5 - 1 GPa) which hints towards
the possible existence of two phases with different Tc. At a pressure above
1.38GPa, the Tconset remains invariant at 10 K but the Tc(\r{ho}=0) is
increased to above 8.2 K. There is a possible transformation from a low Tc
phase to a high Tc phase by application of pressure.
