Abstract

Submicrometric Ni wires have been obtained by electron beam lithography to study their magnetic behavior by magnetotransport measurements. The magnetization reversal of these patterned nanostructures is driven by a combination of two mechanisms: coherent rotation processes, that govern the rotation when the magnetization direction of the lines is away from wire axis, and incoherent curling mechanisms that drive the reversal when the magnetization is closely parallel to line direction.
