Мезоскопічна взаємодія Дзялошинскього-Морія: геометрічне керування магнітокіральністю

Crystals with broken inversion symmetry can host fundamentally appealing and technologically relevant periodical or localized chiral magnetic textures. The type of the texture as well as its magnetochiral properties are determined by the intrinsic Dzyaloshinskii-Moriya interaction (DMI), which is a material property and can hardly be changed. Here we put…

Vortex polarity switching by a spin-polarized current

Authors: Jean-Guy Caputo, Yuri Gaididei, Franz G. Mertens, Denis D. Sheka, Publication: Phys. Rev. Lett. 98, 056604 (2007), 10.1103/PhysRevLett.98.056604 Comments: 4 pages, 3 figures arXiv: http://arxiv.org/abs/cond-mat/0607362 The spin-transfer effect is investigated for the vortex state of a magnetic nanodot. A spin current is shown to act similarly to an effective magnetic field…
