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

Variational Principles of Micromagnetics Revisited
TL;DR: The authors revisited the basic variational formulation of the minimization problem associated with the micromagnetic energy, with an emphasis on the treatment of the stray field contribution to the energy.

Thickness dependent magnetization dynamics of perpendicular anisotropy Co/Pd multilayer films
TL;DR: In this paper, the magnetization properties of sputtered multilayer films were analyzed as a function of Co layer thicknesses and applied bias field, and a concomitant 2.6-fold increase in the damping of the oscillations was observed and attributed to stronger interface dissipation in thinner Co layers.

Domain wall manipulation in magnetic nanotubes induced by electric current pulses.
TL;DR: It is shown that proper interplay between the tube geometry, magnitude of the electric current and the duration of a current pulse, can be used to manipulate the position, velocity and chirality of a vortex domain wall.

Modulation of monocytic leukemia cell function and survival by high gradient magnetic fields and mathematical modeling studies.
TL;DR: It is demonstrated that arrays of high-gradient micrometer-sized magnets induce cell swelling, prolonged increased ROS production, and inhibit cell proliferation, and elicit apoptosis of THP-1 monocytic leukemia cells in the absence of chemical or biological agents.

A constraint-free phase field model for ferromagnetic domain evolution.
Min Yi,Bai-Xiang Xu +1 more
TL;DR: A continuum constraint-free phase field model is proposed to simulate the magnetic domain evolution in ferromagnetic materials that takes the polar and azimuthal angles (ϑ1,ϑ2), instead of the magnetization unit vector m(m1,m2,m3), as the order parameters.

Amihay Hanany,Edward Witten +1 more
TL;DR: In this article, the Coulomb branch of certain three-dimensional supersymmetric gauge theories and the moduli spaces of magnetic monopoles are explained via string theory, and new phase transitions in three dimensions as well as new infrared fixed points and even new coupling constants are predicted from the string theory construction.
