From: Morphology and magnetic properties of Fe3O4 nanodot arrays using template-assisted epitaxial growth
SEM images for the PAA templates and Fe 3 O 4 dot arrays. (a) Ultrathin PAA template, (b) cross section of the PAA, (c) Fe3O4 nanodot array together with a partially removed PAA template, and Fe3O4 nanodot arrays with various sizes - the average dot sizes and inter-dot periods are (d) approximately 40 and approximately 67 nm, (e) approximately 70 and approximately 115 nm, and (f) approximately 140 and approximately 160 nm, respectively.
