Abstract
We present a joint magnetic force microscopy analysis and Magneto-optical K err measurements of dot arrays that contain elliptical elements with differ ent shape. In particular we have investigated the influence of the element shape on the domain structure in the remnant state. The single- or multiple domain nature of the magnetization at remanence is shown to depend strongl y on how rounded or pointed each element is.
