Abstract Motivated by recent reports of a quantum-disordered ground state in the triangular lattice compound NaRuO2, we derive a j eff = 1/2 magnetic model for this system by means of first-principles calculations. The pseudospin Hamiltonian is domin

Abstract Motivated by reports of metallic behavior in the recently synthesized RuI3, in contrast to the Mott-insulating nature of the actively discussed α-RuCl3, as well as RuBr3, we present a detailed comparative analysis of the electronic and magn

The families of organic charge-transfer salts κ-(BEDT-TTF)2X and κ-(BETS)2X, where BEDT-TTF and BETS stand for the organic donor molecules C10H8S8 and C10H8S4Se4, respectively, and X for an inorganic electron acceptor, have been proven to serve as

The low temperature magnetic properties of organic Mott insulator κ-(ET)2-Cu2(CN)3 a quantum spin liquid candidate is notoriously difficult to understand. Here, a model based on defect spins is introduced that allows to describe results of complemen

The observation of magnetic excitation continua in putative Kitaev spin liquid compounds is consistent with predictions of exotic quantum behavior, attracting significant interest. Here, the authors show the observed continua could instead be a conse

Motivated by the recent wealth of exotic magnetic phases emerging in two-dimensional frustrated lattices, we investigate the origin of possible magnetism in the monolayer family of triangular lattice materials $MX_2$ ($M$={V, Mn, Ni}, $X$={Cl, Br, I}

Organic salts represent an ideal experimental playground for studying the interplay between magnetic and charge degrees of freedom, which has culminated in the discovery of several spin-liquid candidates such as $\ensuremath{\kappa}\text{\ensuremath{

In Kitaev materials the spin-orbital entangled nature of the magnetic moments suggests an intricate magnetoelastic coupling. For the case of $\ensuremath{\alpha}$-RuCl${}_{3}$, the authors investigate this effect via first-principles methods. Exact d

In spin-orbit-coupled magnetic materials, the usually applied Curie-Weiss law can break down. This is due to potentially sharp temperature dependence of the local magnetic moments. We therefore propose a modified Curie-Weiss formula suitable for anal
