Abstract
The low-temperature negative domain wall (DW) contribution to the resistivi ty observed in expitaxial Fe microstructures has been investigated as a fun ction of film thickness. The DW spin structure changes from Bloch to Neel-l ike with decreasing film thickness. Results suggest that an interplay betwe en orbital effects in the internal magnetic fields near DWs and thin film s urface scattering are at the origin of the observed negative wall contribut ion.
