摘要/Abstract

摘要： Temperature-dependent resistivity, upper critical field $H_{\rm c2}$ and its anisotropy in overdoped superconducting Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_2$ ($x=0.6$-1) single crystals have been measured in steady magnetic fields up to 44 T and low temperatures down to 0.4 K. Analysis using both the quadratic term and power-law fitting demonstrates that the in-plane resistivity $\rho_{ab}(T)$ progressively approaches the Fermi-liquid $T^2$ behavior with increasing K doping and reaches a saturation plateau at $x \approx 0.8$. The temperature dependence of both $H^{ab}_{\rm{c2}}$ and $H^{c}_{\rm{c2}}$ follows the Werthamer-Helfand-Hohenberg model, incorporating orbital and spin paramagnetic effects. For $x \leq 0.8$, the orbital effect dominates for $H \parallel ab$, while the Pauli paramagnetic effect prevails for $H\parallel c$. For $x > 0.8$, the Pauli paramagnetic effect becomes dominant in both crystallographic directions. The anisotropy of $H_{\rm{c2}}(0)$ exhibits a discontinuity in its dependence on K doping concentration with a significant enhancement at $x=0.8$ and a maximum at $x=0.9$. These experimental results indicate that the electron correlation effect is enhanced in the heavily overdoped Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_2$ system where the underlying symmetries are broken due to the Fermi surface reconstruction before $x=0.9$.
