    Abstract

    We report the longitudinal ρxx and transverse Hall ρxy resistivities of epitaxial SrRuO3 (SRO) under varied applied fields. The Hall resistivity, ρxy, is proportional to 1/(T - Tc) in the paramagnetic state of SRO films, where Tc is the asymptotic Curie temperature. The Lorentz resistivity Δρ(H)Lorentz in a fixed magnetic field in the ferromagnetic regime of SRO films is proportional to A(1 - T/Tc)p with p ∼ 0.5. RH is positive for T>125 K and changes sign at T ∼ 125 K for SRO films. The RH remains negative down to low temperatures.
