[19p-143-10] Relationship between Pr-content and superconducting transition temperature of Ce1-xPrxOBiS2 single crystals

〇Masanori Nagao1, Akira Miura2, Yuuji Hanada1, Yuuki Maruyama1, Satoshi Watauchi1, Yoshihiko Takano3, Isao Tanaka1 (1.Univ. Yamanashi, 2.Hokkaido University, 3.NIMS)

Keywords:BiS2-based superconductor, Mixed anion compounds, Valence fluctuation

CeOBiS2超伝導体のCeサイトをPrで置換すると超伝導転移温度が上昇する. これに伴いCe4+の割合が増加することが明らかとなった.
