Résumé
Diverses phases à haut Tc dérivant de Nb3Ge par substitution d'éléments de transition voisins, Mo, Ti, Zr ont été synthétisées par "sputtering" sur substrat chauffé. Le changement de Tc est relié à la variation du nombre moyen d'électrons d et du rayon atomique. Quelques mesures de dHc2/dT ont été effectuées jusque dans des champs magnétiques de 10 T.
Abstract
We have been synthesizing high Tc systems based on Nb3Ge in which another transition metal atom, either Mo, Ti or Zr, is partially substituted for Nb. Systems have been prepared by selectively thermalized sputtering onto heated substrate. The systems investigated allow changes in Tc to be observed due to a variation in the electron per atom ratio as well as due to atom size effects. Some measurements of dHc2/dT at fields up to 10 T have been made.
