摘要

We report the longitudinal ρ_xx and transverse Hall ρ_xy resistivities of epitaxial SrRuO₃ (SRO) under varied applied fields. The Hall resistivity, ρ_xy, is proportional to 1/(T - T_c) in the paramagnetic state of SRO films, where T_c 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/T_c)^p with p ∼ 0.5. R_H is positive for T>125 K and changes sign at T ∼ 125 K for SRO films. The R_H remains negative down to low temperatures.
