| Popis: | Micromagnetic and macromagnetic switching properties of iron microbars produced by electrodeposition into voids patterned by nanoimprint lithography were investigated. The study was focused on microbars with six different aspect ratios. Magnetization along the long axis produced single-domain states in all microbars regardless of their aspect ratio. In the remanent state, magnetization in microbars with smaller aspect ratios resumed the closed magnetic flux configuration. Closed magnetic flux configuration was also found in demagnetized microbars. Individual, as well as the net remanence curves, were extracted from magnetic force microscopy images to verify their agreement with the macroscopic magnetization measurements. |
