Abstract Exchange underpins the magnetic properties of quantum matter. In its most basic form, it occurs through the interplay of Pauli’s exclusion principle and Coulomb repulsion, being referred to as Coulomb or direct exchange. Pauli’s exclusio

Abstract Kitaev exchange, a new paradigm in quantum magnetism research, occurs for 90° metal-ligand-metal links, $${t}_{2g}^{5}$$ t 2 g 5 transition ions, and sizable spin-orbit coupling. It is being studied in honeycomb compounds but also on triang

Abstract The valence electronic structure of magnetic centers is one of the factors that determines the characteristics of a magnet. This may refer to orbital degeneracy, as for j eff = 1/2 Kitaev magnets, or near-degeneracy, e.g., involving the thir

Abstract The lacunar-spinel chalcogenides exhibit magnetic centers in the form of transition-metal tetrahedra. On the basis of density-functional computations, the electronic ground state of an Mo4 13+ tetrahedron has been postulated as single-config

The hexaborides are a family of materials that exhibit an exotic range of low-temperature properties the physics of which is still under debate. Here, the authors adopt ab initio multi-configurational wavefunction theory to investigate the strong cor

Honeycomb iridates are candidates for the realization of a Kitaev spin liquid, displaying properties such as the protection of quantum information. Here, the authors investigate the phase diagram of honeycomb Li2IrO3, using quantum chemistry methods

We report the results of the experimental and theoretical study of the magnetic anisotropy of single crystals of the Co-doped lithium nitride Li2(Li1-xCox)N with x = 0.005, 0.01, and 0.02. It was shown recently that doping of the Li3N crystalline mat
