The appearance of a new type of domain walls - cluster domain walls - in a chiral ferrimagnetic near the angular momentum compensation point was established, the critical velocities of cluster domain walls are shown to be higher in several times than for standard domain walls. The creation of a topological structure of the skyrmion/hopfion-target type in antiferromagnets with perpendicular magnetic anisotropy is theoretically demonstrated, equation of motion for free oscillations of the topological spin texture is derived, and its quasiclassical solution is found.
