摘要: Motivated by the unusual features observed in transport properties of ferromagnetic ``bad metal'' ${\mathrm{SrRuO}}_{3}$, we construct a model incorporating essential realistic structure this nearly cubic material. In particular, show how ${t}_{2g}$ orbital orientation perfectly determines peculiar hybridization matrix, and demonstrate local non-Fermi liquid arise when interactions are switched on. We discuss effects slight deviation from qualitatively. The provides consistent explanation recently optical response ${\mathrm{SrRuO}}_{3}$.
