Suppression of superconductivity by Sb-substitution into CeOBiS2 single crystals
arXiv:2312.11002 · doi:10.1016/j.ssc.2023.115414
Abstract
Sb-substituted CeOBiS2 single crystals with 0.2-1.0 mm size have been successfully grown using CsCl/KCl flux. Sb substitution strongly suppressed the superconductivity in CeOBiS2, and the substitution of more than approximately 4 atomic percent in Bi-site disappeared the superconductivity at a measurement range of above 0.36 K. Furthermore, the drastic change of c-axis lattice parameter was observed in a neighborhood to Sb substitution amount, which maybe suggests the structural transition in CeOBiS2. The Ce valence state of the obtained single crystals was evaluated. However, the established correlations between Ce valence state and superconductivity could not be revealed.
