Pressure-enhanced superconductivity in Eu${}_3$Bi${}_2$S${}_4$F${}_4$

Yongkang Luo, Hui-Fei Zhai, Pan Zhang +3

The pressure effect on the newly discovered charge-transferred BiS${}_2$-based superconductor, Eu${}_3$Bi${}_2$S${}_4$F${}_4$, with a $T_c$ of 1.5 K at ambient pressure, is investigated by t…
