By using Ar ion milling to pattern our wires rather than the conventional lift-off technique, a depinning field as low as ∼2 3 Oe at room temperature is obtained. Comparison with previous results acquired on similar wires with much higher pinning shows that the critical current density scales with the depinning field, leading to a critical current density of ∼2.5 × 1011Am−2 at 250 K. Moreover, when a current pulse with a current density larger than the critical current density is injected, the DW is not necessarily depinned but it can undergo a modification of its spin structure which hinders current-induced DW motion. Hence, reliable propagation of the DW requires an accurate adjustment of the pulsed current density.</dcterms:abstract> <dc:creator>Seo, Sunae</dc:creator> <dc:language>eng</dc:language> <dc:creator>Rhensius, Jan</dc:creator> <dcterms:bibliographicCitation>First publ. in: Journal of Physics D.
