Description

The remanent magnetic states of rows of electrodeposited nanoscale Ni pillars with diameters of 57-120 nm and aspect ratios of up to 2 have been characterized using off-axis electron holography, which measures the magnetic induction within the pillars and the stray field surrounding them. Inhomogeneities in the Ni, resulting from its grain structure, significantly perturb the axial uniformity of the magnetization. The magnetization is reduced from that of pure Ni due to surface oxidation and the co-deposition of impurities. Interactions between the pillars can be deduced from the external field distribution, and vary with the pillar size and spacing
