FRUSTRATIONS IN THE SYSTEM OF BENT DOMAINS OF A THIN MAGNETIC-FILM

Undulation domain structures (UDSs) of thin uniaxial magnetic films ar e studied. Both accurate and approximate expressions of UDSs energy ar e obtained in the case of sinusoidal form of domain walls. Results of calculations of undulation DS energy dependence on its parameters are presented. The equilibrium values of domain period and domain walls be nd amplitude which are functions of magnetic film parameters and film thickness are found for the demagnetized undulation DS. It is shown th at the energy of demagnetized UDS is less than the energy of parallel- stripe structure.
