Temperature-dependent and anisotropic optical response of layered PrCaMnO probed by spectroscopic ellipsometry
M. A. Majidi, E. Thoeng, P. K. Gogoi +9
We study the temperature dependence as well as anisotropy of optical conductivity () in the pseudocubic single crystal PrCaMnO using spectrocopic ellipso…
Probing orbital fluctuations in RVO3 (R = Y, Gd, or Ce) by ellipsometry
J. Reul, A. A. Nugroho, T. T. M. Palstra +1
We study optical excitations across the Mott gap in the multi-orbital Mott-Hubbard insulators RVO3. The multi-peak structure observed in the optical conductivity can be described c…
Hubbard exciton revealed by time-domain optical spectroscopy
Fabio Novelli, Daniele Fausti, Julia Reul +6
We use broadband ultra-fast pump-probe spectroscopy in the visible range to study the lowest excitations across the Mott-Hubbard gap in the orbitally ordered insulator YVO3. Separa…
High-field recovery of the undistorted triangular lattice in the frustrated metamagnet CuFeO2
T. T. A. Lummen, C. Strohm, H. Rakoto +2
Pulsed field magnetization experiments extend the typical metamagnetic staircase of CuFeO2 up to 58 T to reveal an additional first order phase transition at high field for both th…
Collective orbital excitations in orbitally ordered YVO3 and HoVO3
E. Benckiser, R. Rückamp, T. Möller +6
We study orbital excitations in the optical absorption spectra of YVO3 and HoVO3. We focus on an orbital absorption band observed at 0.4 eV for polarization E parallel c. This feat…
Transition between orbital orderings in YVO3
G. R. Blake, T. T. M. Palstra, Y. Ren +2
Evidence has been found for a change in the ordered occupation of the vanadium d-orbitals at the 77K phase transition in YVO3, manifested by a change in the type of Jahn-Teller dis…
