TLDR
Magnetic skyrmions are nanoscale spin configurations that hold promise as information carriers in ultradense memory and logic devices owing to the extremely low spin-polarized currents needed to move them.Abstract:

Nucleation, stability and current-induced motion of isolated magnetic skyrmions in nanostructures
TL;DR: It is demonstrated by numerical investigations that an isolated skyrmion can be a stable configuration in a nanostructure, can be locally nucleated by injection of spin-polarized current, and can be displaced by current-induced spin torques, even in the presence of large defects.

Magnetic skyrmions: advances in physics and potential applications
TL;DR: A review of the underlying physics of the stabilization of skyrmions at room temperature and their prospective use for spintronic applications is discussed in this paper, where the development of topological spintronics holds promise for applications in the mid-term furure, even though many challenges such as the achievement of writing, processing and reading functionalities at room-temperature and in all-electrical manipulation schemes, still lie ahead.

Anisotropic Superexchange Interaction and Weak Ferromagnetism
TL;DR: In this paper, the Anderson theory of superexchange was extended to include spin-orbit coupling and the antisymmetric spin coupling suggested by Dzialoshinski from purely symmetry grounds and the symmetric pseudodipolar interaction were derived.

A thermodynamic theory of “weak” ferromagnetism of antiferromagnetics
TL;DR: In this paper, a thermodynamic theory of weak ferromagnetism of α-Fe 2 O 3, MnCO 3 and CoCO 3 is developed on the basis of landau's theory of phase transitions of the second kind.

A Unified Field Theory of Mesons and Baryons
TL;DR: In this article, the structure of the particle source in the classical theory is calculated, and some qualitative features of the interactions between these particles and mesons are described, and the way in which a non-linear meson field theory of this type may contain its own sources, and how these may be idealised to point singularities, as in the conventional field theories of interacting linear systems, is formulated.
