Investigation of isotope effects on superconducting transition temperature(Tc) is one of the useful methods to examine whether electron-phononinteraction is essential for pairing mechanisms. The layered BiCh2-based (Ch:S, Se) superconductor family is a candidate for unconventional superconductors,because unconventional isotope effects have previously been observed inLa(O,F)BiSSe and Bi4O4S3. In this study, we investigated the isotope effects of32S and 34S in the high-pressure phase of (Sr,La)FBiS2, which has a monocliniccrystal structure and a higher Tc of 10 K under high pressures, and observedconventional-type isotope shifts in Tc. The conventional-type isotope effectsin the monoclinic phase of (Sr,La)FBiS2 are different from the unconventionalisotope effects observed in La(O,F)BiSSe and Bi4O4S3, which have a tetragonalstructure. The obtained results suggest that the pairing mechanisms ofBiCh2-based superconductors could be switched by a structural-symmetry changein the superconducting layers induced by pressure effects.
