India-stabilized-gadolinia and gadolinia-stabilized-India: Their structural and magnetic properties

摘要

Gd2O3-In2O3 solid solutions were synthesized starting with powders of Gd2O3 and In2O3 in the appropriate stoichiometric ratio and heating them in air to temperatures of 1425 °C. Their crystalline structures were determined using high resolution x-ray diffractometry. Cubic, monoclinic, and hexagonal phases were observed for different compositions. The present study demonstrates that large quantities of the high pressure phases of either Gd2O3 or In2O3 can be obtained in the solid solutions of Gd2-xInxO3 (0 < x < 1.6). The solid solutions show increasing paramagnetic response with increasing Gd content deriving from the Gd3+:4f7 ground sate configuration.
