Abstract
Magnetic submicron cobalt dots with geometrical dimensions comparable to the width of magnetic domains are studied by high resolution magnet ic force microscopy. This study reveals a variety of intricate domain patterns controlled by the details of the dot geometry. The width of t he geometrically constrained magnetic domains can be tuned by changing the thickness of the dots. Theoretical investigation of the domain st ructure in the dots accurately describes the domain pattern and the nu mber of domains per dot.
