Magnetic nanowires as permanent magnet materials
TL;DR: In this paper, the fabrication of metallic magnetic nanowires using a low temperature chemical process is described and shown to have very high coercivity (6.5kOe at 140k and 4.8k Oe at 300k).

Dipolar interactions in arrays of ferromagnetic nanowires: a micromagnetic study
TL;DR: In this paper, the behavior of periodic arrays of magnetic nanowires by micromagnetic simulations using the Nmag modeling package is explored and it is shown that finite size models fail to capture some of the features of real infinite systems.

TL;DR: The bottom-up epitaxial solution growth of high-density arrays of vertical 5 nm diameter single-crystalline metallic cobalt nanowires on wafer-scale crystalline metal surfaces is presented, which bypasses the need of assembling and orientating free colloidal nanocrystals on surfaces.

Anisotropy of domain wall resistance
Michel Viret,Yves Samson,Patrick Warin,Alain Marty,F. Ott,E. Sondergard,Olivier Klein,Claude Fermon +7 more
TL;DR: The resistive effect of domain walls in FePd films with perpendicular anisotropy was studied experimentally as a function of field and temperature and values are consistent with the predictions of Levy and Zhang.

Giant Anisotropic Magneto-Resistance in ferromagnetic atomic contacts
TL;DR: In this article, it was shown that the anisotropy of magneto-resistance is greatly enhanced in atomic size constrictions by a change in the electronic density of states in the junction when the magnetization is rotated, as supported by ab initio calculations.
