Evidence of electronic phase separation in the strongly correlated semiconductor YbB12
A. Azarevich, N. Bolotina, O. Khrykina +9
The studies of high-quality single-domain crystals of YbB12 were carried out by the precise x-ray diffraction technique in combination with the low temperature polarized THz - infr…
Out-of-equilibrium electrons lead to record thermionic emission in LaB6 with the Jahn-Teller instability of boron cage
Elena S. Zhukova, Boris P. Gorshunov, Martin Dressel +11
Materials with low electron work function are of great demand in various branches of science and technology. LaB6 is among the most effective electron-beam sources with one of the…
Low-Energy Excitations in Quantum Spin-Liquids Identified by Optical Spectroscopy
A. Pustogow, Y. Saito, E. Zhukova +6
The electrodynamic response of organic spin liquids with highly-frustrated triangular lattices has been measured in a wide energy range. While the overall optical spectra of these…
Quantum Spin Liquids Unveil the Genuine Mott State
A. Pustogow, M. Bories, A. Löhle +14
The Widom line identifies the locus in the phase diagram where a supercritical gas crosses over from gas-like to a more liquid-like behavior. A similar transition exists in correla…
Origin of Low-Energy Excitations in Charge-Ordered Manganites
E. Zhukova, B. Gorshunov, T. Zhang. +5
The low-energy excitations in the charge-ordered phase of polycrystalline La0.25Ca0.75MnO3 are explored by frequency-domain terahertz spectroscopy. In the frequency range from 4 cm…
Charge Localization due to RKKY Interaction in the Spin Glass AuFe
B. Gorshunov, A. S. Prokhorov, S. Kaiser +11
Measurements of electrodynamic response of of spin glass AuFe films in comparison with pure gold films are performed at frequencies from 0.3 THz (10 cm-1) up to 1000 THz (33000 cm-…
