Résumé
Le GIG (Gadolinium Iron Garnet) amorphe qui ne contient aucun des oxydes ordinaires formant habituellement les verres (B2O3, SiO2 ou P2O5,) est obtenu par le refroidissement rapide. Le spectre Mössbauer du GIG amorphe présente deux maxima à la température ambiante, tandis qu'à 4,2 K on obtient un sextuplet symétrique correspondant à un champ hyperfin de 460 kOe.
Abstract
Amorphous GIG (Gadolinium Iron Garnet) whose constituent contains none of the usual glassforming oxides such as B2O3, SiO2 or P2O5, was obtained by rapid quenching. The Mössbauer spectrum of the amorphous GIG at room temperature was a doublet, while the spectrum at 4.2 K was a symmetrical six-finger pattern due to a hyperfine field, 460 kOe.
