Description
The absorption of small amounts of hydrogen has no noticeable effect on Tc while there are drastic modifications of the magnetic properties: we observe a strong decrease of the low-field susceptibility and a suppression of the higher-field hysteresis. These results can be explained if one admits that hydrogen modifies essentially the inter and intragrain Josephson couplings as well as the percolative morphology of the superconducting regions through the formation of a hydride
Abstract (French)
L'absorption de faibles quantites d'hydrogene n'a pas d'effet notable sur Tc mais change profondement les proprietes magnetiques: il y a, a la fois, diminution de la susceptibilite en champ faible et suppression de l'hysterese en champ plus fort. Ces resultats indiquent que l'hydrogene modifie essentiellement les couplages Josephson inter et intragrains et la morphologie de percolation des zones supraconductrices par formation d'un hydrureAdditional details
