[en] We have investigated the effect of La doping and high pressure on superconducting properties of EuBiS₂F, which is a newly discovered superconducting material (T _c ∼ 0.3 K) (Zhai et al (2014) Phys. Rev. B 90 064518). An enhancement of T _c to 2.2 K is observed in Eu_0.5La_0.5BiS₂F. Upon application of pressure T _c is further enhanced up to ∼10 K (P = 2.5 GPa). Eu_0.5La_0.5BiS₂F is semiconducting down to 3 K. The onset of a superconductivity-like feature is seen at 2.2 K at ambient pressure. At a pressure above 1.38 GPa, the ${T_{\mathrm{c}}}^{\mathrm{o}\mathrm{n}\mathrm{s}\mathrm{e}\mathrm{t}}$ remains invariant at 10 K but the T _c(ρ = 0) is increased to above 8.2 K. There is a possible crystallographic transformation by application of pressure from a structure of low T _c to a structure corresponding to high T _c. (paper)
