Skyrmionic order and magnetically induced polarization change in lacunar spinel compounds GaVS and GaMoS: comparative theoretical study
S. A. Nikolaev, I. V. Solovyev
We show how low-energy electronic models derived from the first-principles electronic structure calculations can help to rationalize the magnetic properties of two lacunar spinel c…
Fingerprints of spin-current physics on magnetoelectric response in the spin- magnet BaCuGeO
Ryota Ono, Sergey Nikolaev, Igor Solovyev
The single-site anisotropy vanishes for the spin-1/2 as a consequence of Kramers degeneracy. We argue that similar property holds for the magnetically induced electric polarization…
Microscopic theory of electric polarization induced by skyrmionic order in GaVS
S. A. Nikolaev, I. V. Solovyev
The lacunar spinel GaVS was recently suggested to be a prototype multiferroic material hosting skyrmion lattice states with a sizeable polarization cou…
Spin dependence of ferroelectric polarization in the double exchange model for manganites
I. V. Solovyev, S. A. Nikolaev
The double exchange (DE) model is systematically applied for studying the coupling between ferroelectric (FE) and magnetic orders in several prototypical types of multiferroic mang…
Orbital Polarization in Itinerant Magnets
I. V. Solovyev
We propose a parameter-free scheme of calculation of the orbital polarization (OP) in metals, which starts with the strong-coupling limit for the screened Coulomb interactions in t…
Electronic Structure of Strongly Correlated Systems Emerging from Combining Path-Integral Renormalization Group with Density Functional Approach
Yoshiki Imai, Igor V. Solovyev, Masatoshi Imada
A new scheme of first-principles computation for strongly correlated electron systems is proposed. This scheme starts from the local-density approximation (LDA) at high-energy band…
