Auteurs : RBID : ISTEX:10909_1986_Article_BF00684005.pdfAbstract
Measurements have been made of the total time required for the penetration of magnetic flux into cylindrical specimens of pure indium and pure tin, both type I superconductors, when an overcritical axial magnetic field is suddenly applied. Whereas previous measurements covered small excess fields, the present measurements extend over magnetic fields more than ten times the critical field. The results show that flux penetrates faster than predicted by the generalized theory recently proposed by Gauthier and Rochon and this may be due to the occurrence of an appreciable magnetoresistance in the specimens as observed in these measurements. A complete theory of the flux penetration process must take into account a specimen conductivity that varies during the penetration itself.
