TL;DR
This study investigates how the domain wall structure in epitaxial Fe wires affects their magnetoresistance, revealing a negative contribution influenced by orbital effects and surface scattering as the film thickness varies.
Contribution
It demonstrates the impact of domain wall spin structure transitions on resistivity and identifies the interplay of orbital effects and surface scattering as key factors.
Findings
Negative domain wall contribution varies with film thickness
Transition from Bloch to Neel-like domain walls observed
Orbital effects and surface scattering influence resistivity
Abstract
The low temperature negative domain wall (DW) contribution to the resistivity observed in expitaxial Fe microstructures has been investigated as a function of film thickness. The DW spin structure changes from Bloch to Neel-like with decreasing film thickness. Results suggest that an interplay between orbital effects in the internal magnetic fields near DWs and thin film surface scattering are at the origin of the observed negative wall contribution.
