Study of superconductors of the second type in the lead-thallium system; Etude des supraconducteurs de la deuxieme espece du systeme plomb-thallium

Abstract

The author has shown by magnetization measurements on lead-thallium alloys having from 5 to 70 atom per cent of thallium, that superconductors of the second type definitively exist. The results obtained, in particular on the upper critical field H{sub C2} are in good agreement with the models of Ginzburg, Landau, Abrikosov, Gorkov and Goodman. Finally resistivity measurements have confirmed the occurrence of a fourth upper critical field, the existence of which has been theoretically predicted by St James and de Gennes. (author) [French] L'auteur par des mesures d'aimantation sur les alliages plomb-thallium, de composition variant de 5 pour cent a 70 pour cent At. de thallium, a montre qu'il fallait admettre definitivement l'existence des supraconducteurs de la deuxieme espece. Les resultats obtenus, en particulier sur le champ critique superieur H{sub c2} sont en bon accord avec les modeles de Ginzburg, Landau, Abrikosov, Gorkov et Goodman. Enfin des mesures de resistivite ont confirme l'existence d'un quatrieme champ critique superieur H{sub c3}, existence prevue theoriquement par St James et de Gennes. (auteur)
