Exchange interactions and magnetic force theorem
I. V. Solovyev
We critically reexamine the problem of interatomic exchange interactions, which describe the total energy change caused by infinitesimal rotations of spins near some equilibrium st…
Microscopic origin of ferromagnetism in trihalides CrCl and CrI
Omar Besbes, Sergey Nikolaev, Igor Solovyev
Microscopic origin of the ferromagnetic (FM) exchange coupling in CrCl and CrI, their common aspects and differences, are investigated on the basis of density functional th…
Superexchange theory of electronic polarization driven by relativistic spin-orbit interaction at the half-filling
I. V. Solovyev
By applying Berry-phase theory for the effective half-filled Hubbard model, we derive an analytical expression for the electronic polarization driven by the relativistic spin-orbit…
Origin of Multiferroicity in MnWO4
I. V. Solovyev
MnWO4 is regarded as a canonical example of multiferroic materials, where the multiferroic activity is caused by a spin-spiral alignment. We argue that, in reality, MnWO4 has two s…
Magnetic structure of hexagonal YMnO3 and LuMnO3 from a microscopic point of view
I. V. Solovyev, M. V. Valentyuk, V. V. Mazurenko
The aim of this work is to unravel a basic microscopic picture behind complex magnetic properties of hexagonal manganites. For these purposes, we consider two characteristic compou…
Magnetic structure of noncentrosymmetric perovskites PbVO3 and BiCoO3
I. V. Solovyev
It is well known that if a crystal structure has no inversion symmetry, it may allow for Dzyaloshinskii-Moriya magnetic interactions, operating between different crystallographic u…
