Abstract

We show that continuous and spin-lattice models of chiral ferro- and antiferromagnets provide the existence of an infinite number of stable soliton solutions of any integer topological charge. A detailed description of the morphology of new skyrmions and the corresponding energy dependencies are provided. The considered model is general, and is expected to predict a plethora of particle-like states which may occur in various chiral magnets including atomic layers, e.g., PdFe/Ir(111), rhombohedral GaV4_4S8_8 semiconductor, B20-type alloys as Mn1x_{1-x}Fex_xGe, Mn1x_{1-x}Fex_xSi, Fe1x_{1-x}Cox_xSi, Cu2_2OSeO3_3, acentric tetragonal Heusler compounds.
