Аннотация:The normal-state charge transport is studied systematically in high-quality single crystals of ${\text{BaFe}}_{2}{({\text{As}}_{1\ensuremath{-}x}{\text{P}}_{x})}_{2}$ $(0\ensuremath{\le}x\ensuremath{\le}0.71)$. By substituting isovalent P for As, the spin-density-wave (SDW) state is suppressed and the dome-shaped superconducting phase $({T}_{c}\ensuremath{\lesssim}31\text{ }\text{K})$ appears. Near the SDW end point $(x\ensuremath{\approx}0.3)$, we observe striking linear temperature $(T)$ dependence of resistivity in a wide $T$ range, and remarkable low-$T$ enhancement of Hall-coefficient magnitude from the carrier number estimates. We also find that the magnetoresistance apparently violates the Kohler's rule and is well scaled by the Hall angle ${\ensuremath{\Theta}}_{H}$ as $\ensuremath{\Delta}{\ensuremath{\rho}}_{xx}/{\ensuremath{\rho}}_{xx}\ensuremath{\propto}{\text{tan}}^{2}\text{ }{\ensuremath{\Theta}}_{H}$. These non-Fermi-liquid transport anomalies cannot be attributed to the simple multiband effects. These results capture universal features of correlated electron systems in the presence of strong antiferromagnetic fluctuations.
