Nonmonotonic Evolution of the Blocking Temperature in Dispersions of Superparamagnetic Nanoparticles
D. Serantes, D. Baldomir, M. Pereiro +3
We use a Monte Carlo approach to simulate the influence of the dipolar interaction on assemblies of monodisperse superparamagnetic nanoparticles. We have identified…
Rapidly fluctuating orbital occupancy above the orbital ordering transition in spin-gap compounds
B. Rivas-Murias, H. D. Zhou, J. Rivas +1
Several spin systems with low dimensionality develop a spin-dimer phase within a molecular orbital below TS, competing with long-range antiferromagnetic order. Very often, preferen…
Study of the pressure effects in TiOCl by ab initio calculations
A. Piñeiro, V. Pardo, D. Baldomir +4
Electronic structure calculations on the low dimensional spin-1/2 compound TiOCl were performed at several pressures in the orthorhombic phase, finding that the structure is quasi-…
The role of doping and dimensionality in the superconductivity of NaxCoO2
M. Banobre-Lopez, F. Rivadulla, R. Caudillo +3
We report a complete analysis of the formal oxidation state of Co in NaxCoO2, in the interval 0.31<x<0.67. Iodometric titration and thermoelectric power confirm that a direct relat…
