Abstract

We extract the paramagnetic anomalous Hall effect (AHE) resistivity ρxyAHE in thin films of the itinerant ferromagnet SrRuO ₃ and show that the AHE coefficient R _s scales with the longitudinal resistivity ρ _xx. We fit the resistivity dependence of ρxyAHE assuming two mechanisms: side jumps and Karplus-Luttinger (Berry phase) mechanism. For the latter, we consider the effect of a finite scattering time with a fractional power-law relation to ρ _xx.
