Local electronic structure of the Co2+ ions in the disordered perovskite phase of Ba3CoNb2O9: a temperature-dependent X-ray absorption and magnetic circular dichroism study

M. M. Ferreira-Carvalho, S. H. Chen, S. Rößler +11

We performed temperature-dependent X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD) measurements on the disordered phase of Ba${}_3$CoNb${}_2$O${}_9$ to d…
