Résumé
La profondeur de pénétration λ dans des films superconducteurs granulaires d'aluminium Al-Al2O3 a été mesurée en fonction de la résistivité à l'état normal ρn, et de la température T. Les résultats indiquent que λ ∝ ρ1/2n. La dégradation des performances des SQUIDS à grandes valeurs de λ est discutée.
Abstract
The magnetic pénétration depth λ in granular Al-Al2O3 superconducting films has been measured as a function of the normal state resistivity ρn and température T. It was found that λ ∝ ρ1/2n up to resistivities of the order of 10000 µΩ-cm. The degradation of SQUID performance on increasing λ will be discussed.
