Modulated and Localized Structures in Cubic Helimagnets

Chiral modulated magnetic states in noncentrosymmetric crystals may theoretically arise as one-dimensional cycloids or conical helices or multidimensional textures, so called Skyrmions or vortex lattices. The micromagnetic equations for different modulated phases are derived and the main features in applied magnetic fields are discussed. The stability of these modulated states may be expressed in terms of the ratio of two experimentally meaningful parameters, the period of a helix and the classical width of a domain wall.     «
