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…

Equilibrium magnetization states in spherical shells of a magnetically soft ferromagnet form two out-of-surface vortices with codirectionally magnetized vortex cores at the sphere poles: (i) a whirligig state with the in-surface magnetization oriented along parallels is typical for thick shells; (ii) a three dimensional onion state with the in-surface meridional…
A ribbon is a surface swept out by a line segment turning as it moves along a central curve. For narrow magnetic ribbons, for which the length of the line segment is much less than the length of the curve, the anisotropy induced by the magnetostatic interaction is biaxial, with…
When: Friday, May 10 at 12:20 Where: Faculty of Radio Physics, Electronics and Computer Systems What: Magnonics and Magnonic Crystalls Who: Anastasiia Korniienko Magnonics is the field of science referring to information transport and processing by spin waves. Magnons are the quanta of spin waves. They have advantages offering more efficient concepts for data transport and processing.…
When: Monday, February 27 at 12:00 Where: Bogolybov Institute of Theoretical Physics What: Curvature effects in AFM nanowiers and their perspectives in spintronics Who: Denis Kononenko Antiferromagnetic materials are of gread interest for theoretical and experimental spintronics due to their SHF properties. We will discuss modern achievements in spintronics of antiferromagnets.
Extending planar two-dimensional structures into the three-dimensional space has become a general trend in multiple disciplines, including electronics, photonics, plasmonics and magnetics. This approach provides means to modify conventional or to launch novel functionalities by tailoring the geometry of an object, e.g. its local curvature. In a generic electronic system,…
Manipulation of the domain wall propagation in magnetic wires is a key practical task for a number of devices including racetrack memory and magnetic logic. Recently, curvilinear effects emerged as an efficient mean to impact substantially the statics and dynamics of magnetic textures. Here, we demonstrate that the curvilinear form of the exchange…
The domain wall motion along a helix-shaped nanowire is studied for the case of spin-current driving via the Zhang-Li mechanism. The analysis is based on the collective variable approach. Two effects are ascertained: (i) the curvature results in the appearance of the Walker limit for a uniaxial wire, and (ii)…
TexStudio is our favorite TeX editor. It works with only SVN version system. Nevertheless, using macroses one can teach it to work with Git also. To do it, one needs to create three new scripts Macros -> Add/Change in the file menu. Get from server %SCRIPT buildManager.runCommand(“git pull “, editor.fileName())
