Abstract

The composite structure characterized in that it presents a superconducting-current density higher than 10<10> A/m<2>, said composite structure comprising: a first layer of magnetic material with uniaxial anisotropy a second barrier-sheet or insulating layer and a third layer of high-temperature superconducting material these layers being arranged, in the described order, on a base substrate. The process for the preparation of a composite structure that presents a superconducting-current density higher than 10<10> A/m<2>, comprises: a) the epitaxial growth of a first layer of magnetic material, a second barrier sheet layer, and a third layer of superconducting material, on a base substrate b) the heating of the base substrate to a temperature ranging from 650 DEG C to 900 DEG C before carrying out the growth of each one of the three layers of step a) and c) the application of an oxygen partial pressure during the growth of each layer.
