Spin Glass Behavior in the Dy3-xYxTaO7 System
J. Francisco Gomez-Garcia, Roberto Escudero, Gustavo Tavizon
Several x-compositions of the polycrystalline Dy3-xYxTaO7 system, crystallizing in the weberite-type structure, were synthesized and structurally characterized using Rietveld refin…
Magnetic Behaviour of the Pyrochlore Solid Solution
C. Cosio-Castaneda, P. de la Mora, F. Morales +2
The temperature dependence of magnetic susceptibility of the BiSrIrO system was studied from 2 to 300 K. According to these measurements, the solid soluti…
Aluminium and carbon doped MgB2: band filling, band shift, and anisotropy loss
Sabina Ruiz-Chavarria, Gustavo Tavizon, Pablo de la Mora
In this work the effect of Carbon and Aluminium doping on the multiband MgB2 superconductor is analyzed. Using the rigid band and virtual crystal approximations (RBA and VCA), it w…
The loss of anisotropy in MgB2 with Sc substitution and its relationship with the critical temperature
Sabina Ruiz-Chavarria, Gustavo Tavizon, Pablo de la Mora
The electrical conductivity anisotropy of the sigma-bands is calculated for the (Mg,Sc)B2 system using a virtual crystal model. Our results reveal that anisotropy drops with relati…
Anisotropic normal-state properties of the MgB2 superconductor
Pablo de la Mora, Miguel Castro, Gustavo Tavizon
Based on the experimentally found existence of two gaps in MgB2 (one gap associated to the boron sigma-states and the other to the boron pi-states), the different contributions to…
Comparative Study of the Electronic Structure of Alkaline-earth Borides (MeB2; Me=Mg, Al, Zr, Nb, and Ta) and their Normal-State Conductivity
Pablo de la Mora, Miguel Castro, Gustavo Tavizon
By means of density functional theory the electronic structure of the MgB2 superconductor was characterised and compared with that of the related iso-structural systems: AlB2, ZrB2…
