Structural changes induced by heat treatment of yttrium-aluminosilicate glasses doped with gadolinium were studied by thermal differential analysis, X-ray diffraction and Gd 3+ electron paramagnetic resonance (EPR). A small amount of yttrium was replaced by gadolinium in the host glass because yttrium and gadolinium cations are quite similar, and gadolinium can be used as a structural sensor by electron paramagnetic resonance measurements. EPR results evidence small changes in the surroundings of Gd 3+ ions in the heat treated samples, as compared with the as prepared ones.

The defect structure of barium titanate ( BaTiO 3) heat-treated under reduced p O 2 has been investigated by electron paramagnetic resonance (EPR) spectroscopy. The results confirm the formation of [Formula: see text]-centers. Based on the relative size of the principal values of the electron g-matrix, g⊥ > g‖, the local distortion of the oxygen octahedron about the [Formula: see text]-centers was also analyzed and the formation of [Formula: see text] defect associates unambiguously established.
