Abstract
Glasses with gadolinium ions xGd2O3(1-x)[0.15Bi2O3 - 0.85TeO2], where 0.01LxL0.25, were prepared and
characterized by IR spectroscopy and susceptibility measurements. IR spectroscopic data permitted to
identify some of the structural units characteristic of this glasses and to follow their evolution with
increasing the rare earth oxide content of the samples. Magnetic susceptibility data permitted to observe
the localization of rare earth ions and the evolution of their interactions with increasing their content in
the samples.
