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

Dynamics of Dzyaloshinskii domain walls in ultrathin magnetic films
TL;DR: In this paper, the authors explore a new type of domain wall structure in ultrathin films with perpendicular anisotropy, that is influenced by the Dzyaloshinskii-Moriya interaction due to the adjacent layers.

Future perspectives for spintronic devices
TL;DR: Spintronics is one of the emerging research fields in nanotechnology and has been growing very rapidly as mentioned in this paper, which has led to the discovery of giant magnetoresistance in 1988, which utilized spin-polarized electron transport across a non-magnetic metallic layer.

TL;DR: It is shown that a pair of coupled skyrmions of opposite chiralities can be stabilized in a symmetric magnetic bilayer system by combining Dzyaloshinskii–Moriya interaction (DMI) and dipolar coupling effects and this results set the ground for emerging spintronic technologies where issues concerningSkyrmion stability, nucleation and propagation are paramount.

A Monopole Wall
TL;DR: In this paper, a smoothed-out version of the planar sheet of Dirac monopoles obtained by linear superposition was constructed, representing a domain wall between a vacuum region and a region of constant energy density.

Monopoles in AdS
TL;DR: In this article, a rational map approximation of the monopole energy was proposed, which can be viewed as a smooth non-abelian refinement of the magnetic bag approximation, to which it reverts under some additional approximations.

BPS Magnetic Monopole Bags
TL;DR: In this paper, the authors explore the characteristics of spherical bags made of large numbers of BPS magnetic monopoles, and show that the magnetic field is largely confined to a thin shell at this radius that separates an interior with almost vanishing magnetic and Higgs fields from an exterior region with long-range Coulomb magnetic and higgs fields.
