We address the concomitant metal-insulator transition (MIT) and antiferromagnetic ordering
in the novel pyrochlore iridate Eu 2 Ir 2 O 7 by combining x-ray absorption spectroscopy, x-
ray and neutron diffractions, and density functional theory (DFT)-based calculations. The
temperature dependent powder x-ray diffraction clearly rules out any change in the lattice
symmetry below the MIT, nevertheless a clear anomaly in the Ir-O-Ir bond angle and Ir-O
bond length is evident at the onset of MIT. From the x-ray absorption near edge structure …
