Nanoscale imaging of the electronic and structural transitions in vanadium dioxide
M. M. Qazilbash, A. Tripathi, A. A. Schafgans +8
We investigate the electronic and structural changes at the nanoscale in vanadium dioxide (VO2) in the vicinity of its thermally driven phase transition. Both electronic and struct…
Electronic correlations and unconventional spectral weight transfer in BaFeCoAs
A. A. Schafgans, S. J. Moon, B. C. Pursley +7
We report an infrared optical study of the pnictide high-temperature superconductor BaFeCoAs and its parent compound BaFeAs. We demonstrate that…
Electrodynamics of the vanadium oxides VO2 and V2O3
M. M. Qazilbash, A. A. Schafgans, K. S. Burch +5
The optical/infrared properties of films of vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) have been investigated via ellipsometry and near-normal incidence reflectance mea…
Optical study of interactions in a d-electron Kondo lattice with ferromagnetism
K. S. Burch, A. Schafgans, N. P. Butch +5
We report on a comprehensive optical, transport and thermodynamic study of the Zintl compound YbMnSb, demonstrating that it is the first ferromagnetic Kondo lattice c…
