Relativistic exchange interactions in CrX (X=Cl, Br, I) monolayers
Y. O. Kvashnin, A. Bergman, A. I. Lichtenstein +1
It has been predicted theoretically and indirectly confirmed experimentally that single-layer CrX (X=Cl, Br, I) might be the prototypes of topological magnetic insulators (TMI)…
Band filling control of the Dzyaloshinskii-Moriya interaction in weakly ferromagnetic insulators
G. Beutier, S. P. Collins, O. V. Dimitrova +8
We observe and explain theoretically a dramatic evolution of the Dzyaloshinskii-Moriya interaction in the series of isostructural weak ferromagnets, MnCO, FeBO, CoCO an…
Electronic topological transition and non-collinear magnetism in compressed hcp Co
Y. O. Kvashnin, W. Sun, I. Di Marco +1
Recent experiments showed that Co undergoes a phase transition from ferromagnetic hcp phase to non-magnetic fcc one around 100 GPa. Since the transition is of first order, a certai…
Layer-resolved magnetic exchange interactions of surfaces of late 3d elements: effects of electronic correlations
S. Keshavarz, Y. O. Kvashnin, I. Di Marco +4
We present the results of an ab initio study of magnetic properties of Fe, Co and Ni surfaces. In particular, we discuss their electronic structure and magnetic exchange interactio…
Twisted magnetic patterns: Exploring the Dzyaloshinskii--Moriya vector
V. E. Dmitrienko, E. N. Ovchinnikova, S. P. Collins +6
Magnetism - the spontaneous alignment of atomic moments in a material - is driven by quantum-mechanical `exchange' interactions which operate over atomic distances as a result of t…
Correlated band theory of spin and orbital contributions to Dzyaloshinskii-Moriya interactions
M. I. Katsnelson, Y. O. Kvashnin, V. V. Mazurenko +1
A new approach for calculations of Dzyaloshinskii-Moriya interactions in molecules and crystals is proposed. It is based on the exact perturbation expansion of total energy of weak…
