The results are presented and analysed in the context of models of DW scattering and conventional magnetoresistance (MR) effects in ferromagnetic metals. Microstructures of progressively higher magnetic anisotropy and thus smaller DW widths have been studied, including; bcc Fe, hcp Co and L1◦ FePt. The magnetic domain structure of these materials have been investigated using magnetic force microscopy and micromagnetic simulations. In Fe and Co the dominant sources of low-field MR are ferromagnetic resistivity anisotropy, due to both anisotropic MR (AMR) and the Lorentz MR. In Fe, at low temperature, a novel negative DW contribution to the MR has been found. Hcp Co microstructures show a greater resistivity for current perpendicular to DWs than for current parallel to DWs, that is consistent with a small (positive) DW resistivity and a Hall effect mechanism. High anisotropy L1◦ FePt microstructures show strong evidence for an intrinsic DW contribution to the resistivity. Related studies and future directions are also discussed.</dcterms:abstract> <dc:creator>Kent, Andrew D.</dc:creator> <bibo:uri rdf:resource=""/> </rdf:Description> </rdf:RDF>
