Analyse des propriétés magnétiques de supraconducteurs à température élevée et de leur application en tant qu'aimants permanents.

Analysis of the magnetic properties of HTc superconductors and their application as permanent magnets.

Auteurs : SOSNOWSKI J.

Résumé

In this paper the subject of the trapped flux is considered taking into account the granular structure of the ceramic materials. The model describing the potential barrier height capturing the vortices, which determines the critical current density, magnetic induction distribution and trapped flux are presented for HTc ceramic superconductors. The influence of ceramic material parameters on the trapped flux magnitude is considered at an aim of indicating meaning these parameters, which should be useful for optimizing trapped flux value. Trapped flux has important meaning from the point of view of application of HTc superconductors in the magnetic levitation process, as superconducting bearings, which is also briefly discussed in the paper.
