Ultrafast manipulation of the NiO antiferromagnetic order via sub-gap optical excitation
Xiaocui Wang, Robin Y. Engel, Igor Vaskivskyi +19
Wide-band-gap insulators such as NiO offer the exciting prospect of coherently manipulating electronic correlations with strong optical fields. Contrary to metals where rapid depha…
Measurement of collective excitations in VO by resonant inelastic X-ray scattering
Haowei He, A. X. Gray, P. Granitzka +14
Vanadium dioxide is of broad interest as a spin-1/2 electron system that realizes a metal-insulator transition near room temperature, due to a combination of strongly correlated an…
Ultrafast THz Field Control of Electronic and Structural Interactions in Vanadium Dioxide
A. X. Gray, M. C. Hoffmann, J. Jeong +34
Vanadium dioxide, an archetypal correlated-electron material, undergoes an insulator-metal transition near room temperature that exhibits electron-correlation-driven and structural…
Phase separation in the non-equilibrium Verwey transition in magnetite
Francesco Randi, Ignacio Vergara, Fabio Novelli +9
We present equilibrium and out-of-equilibrium studies of the Verwey transition in magnetite. In the equilibrium optical conductivity, we find a step-like change at the phase transi…
Correlation-driven insulator-metal transition in near-ideal vanadium dioxide films
A. X. Gray, J. Jeong, N. P. Aetukuri +17
We use polarization- and temperature-dependent x-ray absorption spectroscopy, in combination with photoelectron microscopy, x-ray diffraction and electronic transport measurements,…
About the strength of correlation effects in the electronic structure of iron
J. Sanchez-Barriga, J. Fink, V. Boni +13
The strength of electronic correlation effects in the spin-dependent electronic structure of ferromagnetic bcc Fe(110) has been investigated by means of spin and angle-resolved pho…
