Spin dynamics from a constrained magnetic Tight-Binding model
Ramon Cardias, Cyrille Barreteau, Pascal Thibaudeau +1
A dynamics of the precession of coupled atomic moments in the tight-binding (TB) approximation is presented. By implementing an angular penalty functional in the energy that captur…
Dzyaloshinskii-Moriya interaction in absence of spin-orbit coupling
Ramon Cardias, Anders Bergman, Attila Szilva +5
In contrast to conventional assumptions, we show that the Dzyaloshinskii-Moriya interaction can be of non-relativistic origin, in particular in materials with a non-collinear magne…
Theory of non-collinear interactions beyond Heisenberg exchange; applications to bcc Fe
A. Szilva, D. Thonig, P. F. Bessarab +8
We show for a simple non-collinear configuration of the atomistic spins (in particular, where one spin is rotated by a finite angle in a ferromagnetic background) that the pairwise…
