Role of direct exchange and Dzyaloshinskii-Moriya interactions in magnetic properties of graphene derivatives: CF and CH
V. V. Mazurenko, A. N. Rudenko, S. A. Nikolaev +3
According to the Lieb's theorem the ferromagnetic interaction in graphene-based materials with bipartite lattice is a result of disbalance between the number of sites available for…
Spin-orbit coupling and magnetic interactions in Si(111):{C,Si,Sn,Pb}
D. I. Badrtdinov, S. A. Nikolaev, M. I. Katsnelson +1
We study the magnetic properties of the adatom systems on a semiconductor surface Si(111):\{C,Si,Sn,Pb\} - (). On the basis of all-electron density functi…
Hybridization and spin-orbit coupling effects in quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12
D. I. Badrtdinov, O. S. Volkova, A. A. Tsirlin +3
We study electronic and magnetic properties of the quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12 with a distinct orthogonal connectivity of CuO4 plaquettes. An effective low-e…
First-principles study of the magnetic ground state in kagome francisites Cu3Bi(SeO3)2O2X (X=Cl, Br)
S. A. Nikolaev, V. V. Mazurenko, A. A. Tsirlin +1
We explore magnetic behavior of kagome francisites Cu3Bi(SeO3)2O2X (X = Cl and Br) using first-principles calculations. To this end, we propose an approach based on the Hubbard mod…
Band filling dependence of the Curie temperature in CrO2
I. V. Solovyev, I. V. Kashin, V. V. Mazurenko
Rutile CrO is an important half-metallic ferromagnetic material, which is also widely used in magnetic recording. In an attempt to find the conditions, which lead to the increa…
A high-temperature expansion method for calculating paramagnetic exchange interactions
O. M. Sotnikov, V. V. Mazurenko
The method for calculating the isotropic exchange interactions in the paramagnetic phase is proposed. It is based on the mapping of the high-temperature expansion of the spin-spin…
