Magnetic Domains
TLDR
In this paper, a Nahm transform has been discovered for magnetic bags, which are conjectured to arise in the large n limit of magnetic monopoles with charge n, and they are interpreted using string theory and presented some partial proofs of this conjecture.Abstract:
Recently a Nahm transform has been discovered for magnetic bags, which are conjectured to arise in the large n limit of magnetic monopoles with charge n We interpret these ideas using string theory and present some partial proofs of this conjecture We then extend the notion of bags and their Nahm transform to higher gauge theories and arbitrary domains Bags in four dimensions conjecturally describe the large n limit of n self-dual strings We show that the corresponding Basu-Harvey equation is the large n limit of an equation describing n M2-branes, and that it has a natural interpretation in loop space We also formulate our Nahm equations using strong homotopy Lie algebrasread more

Imaging spin textures in advanced magnetic nanostructures using Lorentz microscopy
TL;DR: In this paper, the effect of anti-symmetric exchange induced at the interface of a magnetic thin film, the Dzyaloshinkii-Moriya interaction (DMI), was simulated for magnetic vortices in permalloy (Py) discs.

TL;DR: Magnetization processes and magnetic domain structures in Ta/CoFeB/MgO stacks were studied in a series of samples with various CoFeB thicknesses d ranging from 124 to 160nm with a step of 004nm, using polar magneto-optical Kerr effect (PMOKE) magnetometry and microscopy as mentioned in this paper.

Numerical simulation of the generation of magnetic inhomogeneities in ferromagnets with inhomogeneous parameters
TL;DR: In this article, the generation and evolution of magnetic inhomogeneities of the stationary breather type, which appear in a flat layer with the magnetic anisotropy and exchange interaction parameters that are different from those in the bulk of an infinite ferromagnet after transmission through a 180° domain wall, have been investigated theoretically.

The propagation of shape changing soliton in a nonuniform nonlocal media
TL;DR: In this article, the exact solitary solutions of the nonlinear evolution equation were constructed using the modified extended tangent hyperbolic function method, and the shape changing property of solitons for the given integrable system in the presence of damping as well as inhomogeneities.
