Enhanced dimerization of TiOCl under pressure: spin-Peierls - to - Peierls transition
S. Blanco-Canosa, F. Rivadulla, A. Pineiro +6
We report high-pressure x-ray diffraction and magnetization measurements combined with ab-initio calculations to demonstrate that the high-pressure optical and transport transition…
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…
New low-temperature phases in NaxCoO2 linked to quantum criticality
F. Rivadulla, M. Banobre-Lopez, M. Garcia-Hernandez +2
New electronic phases have been identified and placed in the (T,H) phase diagram of metallic NaxCoO2. At low Na-content (x = 0.36), the magnetic susceptibility diverges with a powe…
Quantum critical behaviour in NaxCoO2
F. Rivadulla, M. Banobre-Lopez, M. A. Lopez-Quintela +1
We report the divergence of the nonlinear component of the bulk susceptibility in NaxCoO2 (0.3<x<0.62) as T goes to 0 K. These experiments provide an striking evidence of the exist…
The origin of the glassy magnetic dynamics of the phase segregated state in perovskites
F. Rivadulla, M. A. Lopez-Quintela, J. Rivas
In this paper we address many of the fundamental open questions regarding the glassy behavior of the magnetic/electronic phase segregated state in rare earth perovskites. In partic…
