Heisenberg and anisotropic exchange interactions in magnetic materials with correlated electronic structure and significant spin-orbit coupling
Vladislav Borisov, Yaroslav O. Kvashnin, Nikolaos Ntallis +8
The Dzyaloshinskii-Moriya (DM) interaction, as well as symmetric anisotropic exchange, are important ingredients for stabilizing topologically non-trivial magnetic textures, such a…
Nature of the magnetic moment of cobalt in ordered FeCo alloy
Arsenii Gerasimov, Lars Nordström, Sergii Khmelevskyi +2
The magnets are typically classified into Stoner and Heisenberg type, depending on the itinerant or localized nature of the constituent magnetic moments. In this work, we investiga…
Current driven magnetization dynamics in helical spin density waves
Ola Wessely, Bjorn Skubic, Lars Nordstrom
A mechanism is proposed for manipulating the magnetic state of a helical spin density wave using a current. In this paper, we show that a current through a bulk system with a helic…
First-principles approach to Non-Collinear Magnetism: towards Spin-dynamics
S. Sharma, J. K. Dewhurst, C. Ambrosch-Draxl +6
A description of non-collinear magnetism in the framework of spin-density functional theory is presented for the exact exchange energy functional which depends explicitly on two-co…
