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

Reduced polynomial invariant integrity basis for in-plane magneto-mechanical loading
TL;DR: In this article , the authors considered a material with cubic symmetry whose texture can be described by one of three fibers denoted as $\theta$, $\gamma$ or ''alpha$ ' , and which is thin enough so that both the stress and the magnetization can be considered as in-plane quantities.

Synchrotron radiation studies of magnetic materials and devices
TL;DR: In this paper, the authors provide insights into a few challenging problems related to both conventional magnetic materials and new generation magnetoelectronic devices intended for data storage and processing, by utilizing the advantages of synchrotron radiation based techniques, which are extremely powerful tools for studying magnetism at the nanoscale.
Controlling the magnetization at the conical apex of a multi-terminal STM probe
TL;DR: In this article, the authors used spin-filter scanning tunnel microscopy (SF-STM) to characterize the magnetization at the conical apex of the tips of the double-tip SF-STMs, where the metal layer stack contains 10 nm gold, 2 to 10 nm cobalt and 5 nm gold.

Influence of boundary geometry in domain wall propagation in magnetic films with asymmetric holes: Micromagnetic calculations
Alejandro Alija,I. Sobrado,G. Rodríguez-Rodríguez,María Vélez,J. M. Alameda,Juan M. R. Parrondo,José Ignacio Martín +6 more
TL;DR: In this paper, the authors have shown that the domain wall propagation is different at the top/bottom boundaries of the simulated film which can be understood in terms of the magnetostatic energy and the chirality of the domain walls.
