Ap. Ges et Vv. Fedotova, THE INFLUENCE OF TRANSFORMATIONS IN (GDCA)(3)(MGZRGA)(5)O-12 GARNET SUBSTRATES ON FILMS PROPERTIES, Crystal research and technology, 33(3), 1998, pp. 477-481
In (GdCa)(3)(MgZrGa)(5)O-12 garnet substrates two regions were found 2
00-300 degrees C and 600-700 degrees C with anomalous dependence of li
near expansion coefficient alpha(T) on temperature (T). This effect ca
uses the appearance of internal stresses, periodically changing in mag
nitude and sign in substrate-film system. The attempt is made to deter
mine the correlation between these stresses and the character of domai
n structure in these films.
