Enhancement of the Nernst effect by stripe order in a high-Tc superconductor
Olivier Cyr-Choiniere, R. Daou, Francis Laliberte +12
The Nernst effect in metals is highly sensitive to two kinds of phase transition: superconductivity and density-wave order. The large positive Nernst signal observed in hole-doped…
Enhanced Pressure Dependence of Magnetic Exchange in A2+[V2]O4 Spinels Approaching the Itinerant Electron Limit
S. Blanco-Canosa, F. Rivadulla, V. Pardo +6
We report a systematic enhancement of the pressure dependence of TN in A2+[V2]O4 spinels as the V-V separation approaches the critical separation for a transition to itinerant-elec…
VO: A Strongly Correlated Metal Close to a Mott- Hubbard Transition
F. Rivadulla, J. Fernandez-Rossier, M. Garcia-Hernandez +3
Here we present experimental and computational evidences to support that rock-salt cubic VO is a strongly correlated metal with Non-Fermi-Liquid thermodynamics and an unusually str…
Suppression of Ferromagnetic Double Exchange by Vibronic Phase Segregation
F. Rivadulla, M. Otero-Leal, A. Espinosa +4
From Raman spectroscopy, magnetization, and thermal-expansion on the system La2/3(Ca1-xSrx)1/3MnO3, we have been able to provide a quantitative basis for the heterogeneous electron…
Suppression of the Magnetic Phase Transition in Manganites Close to the Metal-Insulator Crossover
F. Rivadulla, J. Rivas, J. B. Goodenough
We report the suppression of the magnetic phase transition in La1-xCaxMnO3 close to the localized-to-itinerant electronic transition, i.e. at x = 0.2 and x = 0.5. A new crossover t…
Chemical, Structural, and Transport Properties of Na1-xCoO2
F. Rivadulla, J. S. Zhou, J. B. Goodenough
We report measurement of room-temperature compressibility, thermal expansion, thermoelectric power a(T) at various pressures P < 20 kbar, basal-plane resistivity rab (T), magnetic…
