- 論文の詳細を見る
We have performed electrical resistivity measurements of a polycrystalline sample of FeSe0.25Te0.75, which exhibits superconductivity at $T_{\text{c}}\sim 14$ K, in magnetic fields up to 55 T to determine the upper critical field $\mu_{0}H_{\text{c2}}$. In this compound, very large slopes of $\mu_{0}H_{\text{c2}}$ at the onset, the mid-point, the zero-resistivity temperatures on superconductivity are determined to be $-13.7$, $-10.1$, and $-6.9$ T/K, respectively. The observed $\mu_{0}H_{\text{c2}}(T)$s of this compound are considerably smaller than those expected from the Werthamer–Helfand–Hohenberg model, manifesting the Pauli limiting behavior. These results suggest that this compound shows the spin-singlet pairing in the superconducting state.
