Entangled orbital, spin, and ferroelectric orders in -electron magnet CsO
Ryota Ono, Ravi Kaushik, Sergey Artyukhin +3
Alkali superoxides differ from conventional transition metal magnets, exhibit magnetism from partially occupied oxygen molecular -orbitals. Among them, CsO stands out for…
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…
Exchange interactions of CaMnO3 in the bulk and at the surface
Samara Keshavarz, Yaroslav Kvashnin, Debora Rodrigues +7
In this work, we present electronic and magnetic properties of CaMnO3 (CMO) as obtained from ab initio calculations. We identify the preferable magnetic order by means of density f…
Pressure dependence of the structure and electronic properties of Sr3Ir2O7
C. Donnerer, Z. Feng, J. G. Vale +9
We study the structural evolution of SrIrO as a function of pressure using x-ray diffraction. At a pressure of 54 GPa at room temperature, we observe a first-order stru…
