L'imagerie par rayonnement térahertz a été utilisée pour diagnostiquer la distribution des supercourants et des vortex dans des environnements à haute température.Tc bandes de couches minces supraconductrices. Nous les observons dans les films YBCO imprimés dans la bande avec et sans réseaux ordonnés de petits antipoints. La comparaison avec la distribution théoriquement attendue révèle que la technique actuelle peut fournir un outil puissant pour l'évaluation sans contact, non destructive et en espace libre de la distribution du supercourant et du vortex avec un bon accord quantitatif. L'effet de la formation d'antidots dans les bandes s'explique par la diminution du courant critique effectif. L'état rémanent après la suppression du champ magnétique relativement important ne peut pas être expliqué par le modèle conventionnel pour les films minces supraconducteurs, et la divergence est plus notable dans la zone formée par l'antidot.

Abstract: Terahertz radiation imaging has been employed to diagnose the supercurent and vortex distribution in high-Tc superconductive thin film strips. We observe them in the YBCO films patterned into the strip with and without ordered arrays of small antidots. Comparison with the theoretically expected distribution reveals that the present technique can provide a powerful tool for the noncontact, nondestructive, and free-space evaluation of the supercurrent and the vortex distribution with good quantitative agreement. The effect of the antidot formation in the strips is explained by the decrease of the effective critical current. The remanent state after removal of the relatively large magnetic field cannot be explained by the conventional model for the superconductive thin films, and the discrepancy is more notable in the antidot-formed area.
