Spin-orbit-lattice entangled state in AMgReO (A = Ca, Sr, Ba) revealed by resonant inelastic X-ray scattering
Felix I. Frontini, Graham H. J. Johnstone, Naoya Iwahara +7
The ordered double perovskites present an exotic playground for studying novel multi-polar physics due to large spin-orbit coupling. We present Re L3 edge resonant inelastic…
Anisotropic Coulomb exchange as source of Kitaev and off-diagonal symmetric anisotropic couplings
Pritam Bhattacharyya, Thorben Petersen, Nikolay A. Bogdanov +1
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 re…
Sweet spot in the RuCl magnetic system: nearly ideal moments and maximized ratio under pressure
Pritam Bhattacharyya, Liviu Hozoi, Quirin Stahl +2
Maximizing the ratio between Kitaev and residual Heisenberg interactions is a major goal in nowadays research on Kitaev-Heisenberg quantum magnets. Here we investigate Kitaev-Heise…
Resonating holes vs molecular spin-orbit coupled states in group-5 lacunar spinels
Thorben Petersen, Pritam Bhattacharyya, Ulrich K. Rößler +1
The valence electronic structure of magnetic centers is one of the factors that determines the characteristics of a magnet. It may refer to orbital degeneracy, as for $j_\text{eff}…
NaRuO: Kitaev-Heisenberg exchange in triangular-lattice setting
Pritam Bhattacharyya, Nikolay A. Bogdanov, Satoshi Nishimoto +2
Kitaev exchange, a new paradigm in quantum magnetism research, occurs for 90 metal-ligand-metal links, transition ions, and sizable spin-orbit coupling. It is…
Quantum chemical insights into hexaboride electronic structures: correlations within the boron -orbital subsystem
Thorben Petersen, Ulrich K. Rößler, Liviu Hozoi
The notion of strong electronic correlations arose in the context of -metal oxides such as NiO but can be exemplified on systems as simple as the H molecule. Here we shed li…
