STUDY OF ANOMALIES NEAR 75°C IN LiNbO3 BY X-RAY DIFFRACTION
-
Abstract
The anomaly of LiNbO3 in the vicinity of 75°C has been studied by various X-ray diffraction methods. An abrupt change of axial ratio (c/a) was measured, which may be ascribed to alternate rotation of NbO6 octahedron about c axis. No change of structure symmetry was observed.
