Abstract
Magnetic domain transition is a fascinating phenomenon. The domain transition is triggered to reduce total magnetic energy. If at the maximum energy in single domain, the system can have the highest coercivity. Thus, this transition is linked to applications in developing permanent magnets, since vicinity of critical size for single domain to multi-domain transition makes it possible to achieve the highest coercivity. In this work, we approach this issue with well-known soft magnetic iron by varying the thickness of the iron films. With help of epitaxial synthesis, the vicinity of the critical size for the domain transition could be achieved.
