ENERGY OF UNDULATION DOMAIN-STRUCTURE

The undulation domain structure (UDS) of the thin uniaxial magnetic fi lms is studied. Both rigorous and approximate expressions of UDS energ y are obtained using the magnetic charges method in case of sinusoidal form of domain walls. The results of calculation of UDS energy depend ence on it's parameters are presented. For the demagnetized UDS the eq uilibrium values of domain period and domain walls bend amplitude bein g a function of magnetic film parameters are found. It is shown that t he equilibrium period of demagnetized UDS is greater then the equilibr ium period of stripe domain structure if the ratio of the film charact eristic length and thickness less-than-or-equal-to 0.3
