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

TL;DR: In this paper, the authors show that the asymmetry of the domain walls in a tetragonal multilayered film of the diluted ferromagnetic semiconductor (Ga,Mn) with a stepwise variation of P doping can be explained by Dzyaloshinskii-Moriya interactions.

TL;DR: Several new effects observed like an apparent Young´s modulus softening close to TPM under moderate fields, instead of the hardening outside this range, are explained by microeddy and macroeddy current relaxations that to date have been disregarded.
