LDA+DMFT calculations of the Knight shift and relaxation rate in VOMoO4 — •Amin Kiani and Eva Pavarini — Institute for Advanced Simulation and JARA, Forschungszentrum Jülich, 52425 Jülich, Germany
By using the LDA+DMFT approach and the local vertex approximation, we calculate the magnetic linear response function of strongly correlated transition-metal oxides. From the susceptibility we obtain Knight shift and relaxation rate. We present results for the frustrated system VOMoO4. In particular we investigate how the Knight shift and the relaxation time behave in different temperature and correlation regimes.
