Abstract
L'invention concerne un fluxmètre supra-conducteur à interférence d'un quantum. Selon l'invention, il comprend un moyen 42, 43 pour appliquer un courant alternatif d'excitation ayant plusieurs fréquences f1 , f2 , à un dispositif supra-conducteur à interférence d'un quantum 44, à travers un couplage électromagnétique, un amplificateur 45 amplifiant un courant alternatif ayant une ou plusieurs composantes de fréquence à la sortie du dispositif et un moyen pour détecter un flux magnétique appliqué au dispositif 4 en recevant le courant alternatif amplifié par l'amplificateur 45. L'invention s'applique notamment à l'instrumentation électrique de précision et aux circuits électroniques supra-conducteurs.
