CHARACTERISTIC ASPECTS OF CERAMIC COMPOUNDS CONTAINING YTTERBIUM

Abstract

This paper presents experimental data obtained by its author on superconductive ceramics of type 1-2-3, with ytterbium as the element of rare earth. Thermal, electric and magnetic analyses are presented. The aim of the paper is to put in evidence the effect of the substitution of Yb or Cu with Ga in the compound YbBa 2 Cu 3 O 7-δ, in order to compare these properties of this compound with other compounds from the same class having Y or Eu as rare earth ions.
