Properties of Congruently-Melting LiNbO₃–Fe₂O₃ Solid-Solution Single Crystals

Humihiko Takei and Tōru Katsumata¹

(Received December 28, 1981; accepted for publication April 17, 1982)

The phase transition in single crystals of a congruently-melting LiNbO₃–Fe₂O₃ solid-solution, grown by the Czochralski pulling method, has been investigated using dilatometry. It was found that the Curie point, which corresponded to the phase transition temperature, was greatly lowered by the addition of 0.1 mol% Fe₂O₃. This effect is tentatively explained as a decrease in covalency in the metal-oxygen octahedra.
