Abstract 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 $x=0.9$.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
