In this paper the phase diagrams for uniform states of a rhombic-ferromagnet domain boundary are plotted. The separate domain boundary in a thick ferromagnetic film (the easy axis is in the film plane) is studied. The regions of phase-diagram parameters (nonuniform exchange interaction, rhombic anisotropy, external magnetic field), where the domain boundary has no stable one-dimensional states, are determined. The existence of these regions is a result of the long-range character of magnetic-dipole interaction. It is shown that the transition across the region of multidimensional states by the changes of phase-diagram parameters can lead to the generation of subdomain structure. The expression for the flexural-oscillation spectrum of a plane domain boundary of a rhombic ferromagnet is defined. Both types of relaxation (uniform and exchange) are taken into account in the spectrum of flexural oscillations.
