[en] We correlate the lowering of Tsub(c) due to the introduction of magnetic atoms of praseodymium in the amorphous matrix La75Al25 and La75Ga25, with crystal field effects around Pr3+

Nous avons mesure les temperatures de transition supraconductrice Tsub(c) d'alliages amorphes Lasub(75-x)Prsub(x)Ga25 et Lasub(75-x)Prsub(x)Al25 (0< x<6). Nous correlons l'abaissement de Tsub(c) du a l'introduction d'atomes magnetiques de praseodyme dans les matrices amorphes La3Al et La3Ga au champ cristallin autour des ions Pr3+Journal

[en] We have studied by magnetoresistance measurements weak localization phenomena in the amorphous alloys La68Pr7Al25 and La69Pr6Ga25. Our determination of the superconducting transition temperature (Tsub(C)) in Lasub(75-x)Prsub(x)Al25 and Lasub(75-x)Prsub(x)Ga25 systems made it possible to compute the magnetoresistance due to electron-electron interaction and we find it to be of the same order of magnitude as the localization contribution
