Abstract

SrRuO3 is a 4d itinerant ferromagnet (Tc∼150K) with stripe domain structure. Using high-quality thin films of SrRuO3 we study the resistivity induced by its very narrow (∼3 nm) Bloch domain walls ρDW (DWR), at temperatures between 2 K and Tc as a function of the angle θ between the electric current and the ferromagnetic domains walls. We find that ρDW(T,θ)=sin2θρDW(T,90)+B(θ)ρDW(T,0), which provides the first experimental indication that the angular dependence of spin accumulation contribution to DWR is sin2θ. We expect magnetic multilayers to exhibit a similar behavior.
