Competing spin-orbital singlet states in the 4 honeycomb ruthenate AgLiRuO
T. Takayama, M. Blankenhorn, J. Bertinshaw +25
When spin-orbit-entangled -electrons reside on a honeycomb lattice, rich quantum states are anticipated to emerge, as exemplified by the Kitaev materials. Distinct yet equ…
Optical Stabilization of Fluctuating High Temperature Ferromagnetism in YTiO
A. S. Disa, J. Curtis, M. Fechner +9
In quantum materials, degeneracies and frustrated interactions can have a profound impact on the emergence of long-range order, often driving strong fluctuations that suppress func…
Optical Characteristics of Charge Carrier Transfer across Interfaces between YBaCuO and LaCaMnO
A. Seo, A. V. Boris, G. Cristiani +2
We report a spectral ellipsometry study of multilayers composed of superconducting YBaCuO (YBCO) and ferromagnetic LaCaMnO in the spectral range…
Fano Resonances in the Infrared Spectra of Phonons in Hyper-Kagome Na_3Ir_3O_8
D. Pröpper, A. N. Yaresko, T. I. Larkin +7
We report the complex dielectric function of high-quality Na_3Ir_3O_8 single crystals determined by spectroscopic ellipsometry in the spectral range from 15 meV to 2 eV. The far-in…
Orbital reflectometry
E. Benckiser, M. W. Haverkort, S. Brueck +13
The occupation of d-orbitals controls the magnitude and anisotropy of the inter-atomic electron transfer in transition metal oxides and hence exerts a key influence on their chemic…
Dipole-active optical phonons in YTiO_3: ellipsometry study and lattice-dynamics calculations
N. N. Kovaleva, A. V. Boris, L. Capogna +6
The anisotropic complex dielectric response was accurately extracted from spectroscopic ellipsometry measurements at phonon frequencies for the three principal crystallographic dir…
