- Abstract
In this work we present a study of electronic structure and superconducting properties of the Ca-LaBaCu3O7 system, based on calculations performed by the Full-Potential Linearized Augmented Plane Waves (FP-LAPW) method, within the framework of the density functional theory (DFT), and using the Generalized Gradient Approximation (GGA) for the correlation-exchange potential. We used graphics of energy as a function of volume in order to determine structural characteristics as cohesion energy and lattice parameter. It is possible to be observed in the structure that bands, in the normal state, have metallic behavior.
