Increase in the magnitude of the energy barrier distribution in Ni nanoparticles due to dipolar interactions
S. H. Masunaga, R. F. Jardim, R. S. Freitas +1
The energy barrier distribution Eb of five samples with different concentrations x of Ni nanoparticles using scaling plots from ac magnetic susceptibility data has been determined.…
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…
Homopolar bond formation in ZnVO close to a metal-insulator transition
V. Pardo, S. Blanco-Canosa, F. Rivadulla +4
Electronic structure calculations for spinel vanadate ZnVO show that partial electronic delocalization in this system leads to structural instabilities. These are a consequ…
Pressure-induced metal-insulator transition in MgV_2O_4
D. Baldomir, V. Pardo, S. Blanco-Canosa +4
On the basis of experimental thermoelectric power results and ab initio calculations, we propose that a metal-insulator transition takes place at high pressure (approximately 6 GPa…
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…
