Domain structures and magnetization processes in thin magnetic films (3 levels).

Magnetic domains are areas with homogeneously distributed magnetization vector inside. The domains existence was proved by many experiments. But what is the reason for domain appearance in a sample? Domains appear to minimize the total system energy....

Now we know that magnetic domains appear to minimize the total system energy. Indeed, as usually any system try to reach the state in which its total energy becomes minimal one. The domain appearence minimizes the total energy of the sample by a lowering...

Now we analyze magnetization process in a film with the stripe domain structure (DS ) neglecting the domain wall width, see Fig.2. The total volume energy density of DS is the sum of the domain wall, Zeeman and demagnetizing energies: (1.8)...
