Tunable vertical ferroelectricity and domain walls by interlayer sliding in $β$ -ZrI $_{2}$

Xiaonan Ma, Chang Liu, Wei Ren +1

Vertical ferroelectricity where a net dipole moment appears as a result of in-plane ionic displacements has gained enormous attention following its discovery in transition metal di…

Magnetically induced polarization in centrosymmetric bonds

Igor Solovyev, Ryota Ono, Sergey Nikolaev

We reveal the microscopic origin of electric polarization $P$ induced by noncollinear magnetic order. We show that in Mott insulators, such $P$ is given by all possible…

Skyrmionic order and magnetically induced polarization change in lacunar spinel compounds GaV $_{4}$ S $_{8}$ and GaMo $_{4}$ S $_{8}$ : 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- $1/2$ magnet Ba $_{2}$ CuGe $_{2}$ O $_{7}$

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 origin of ferromagnetism in trihalides CrCl $_{3}$ and CrI $_{3}$

Omar Besbes, Sergey Nikolaev, Igor Solovyev

Microscopic origin of the ferromagnetic (FM) exchange coupling in CrCl $_{3}$ and CrI $_{3}$ , their common aspects and differences, are investigated on the basis of density functional th…

Realization of anisotropic compass model on the diamond lattice of Cu $^{2 +}$ in CuAl $_{2}$ O $_{4}$

S. A. Nikolaev, I. V. Solovyev, A. N. Ignatenko +2

Spin-orbit (SO) Mott insulators are regarded as a new paradigm of magnetic materials, whose properties are largely influenced by SO coupling and featured by highly anisotropic bond…
