The dynamic properties of magnetic bubbles, which form in two-dimensional lattices with symmetry space groups P6 and Pabl in the process of self-organization in a pulsed magnetization field, were studied by the method of high-speed photography. Division of domains, which determines the scenarios of the transition from self-organization to chaos, was observed. At all stages of motion the shape of the domain walls was found to be described well by the Cassinian ovals.
