Electronic correlations and spin-orbit coupling in d⁴ osmates — •Vladislav Pokorný¹ and Jan Kuneš² — ¹Center for Electronic Correlations and Magnetism, Institute of Physics, University of Augsburg, Germany — ²Institute of Physics, Academy of Sciences of the Czech Republic, Prague, Czech Republic

We employ the combination of the density functional theory and the dynamical mean-field theory to investigate the electronic correlations in heavy transition metal compounds with partially filled t_2g levels such as d⁴ osmates which were prepared recently. Using the hybridization-expansion, continuous-time quantum Monte Carlo impurity solver we study the combined influence of electron correlations and spin-orbit coupling effects on the the electronic and magnetic structure of these systems.
