Fractal Geometry of a Domain Wall with a Bloch Point in a Cylindrical Ferromagnetic Nanowire
793–802 (2024)

PACS numbers: 05.45.Df, 61.46.Km, 64.60.al,75.40.Mg, 75.60.Ch, 75.75.Fk

As shown, the magnetic structure of the central area of the domain wall that contains the Bloch point of a cylindrical ferromagnetic nanowire is formed in accordance with fractal geometry. The algorithm for constructing of fractal is determined by the directions and chirality of the basis vectors of a primitive vortex cell that located near the localization region of the core of the Bloch point. This conclusion justifies the generalization of the results on the structural properties and their-basis-obtained dynamic ones of the Bloch point, which were studied with magnetic modelling in various nanowires

KEY WORDS: cylindrical ferromagnetic nanowire, domain wall, Bloch point, magnetic structure, primitive vortex cell, fractal
