抄録

According to HAUP measurements, two ferroelectric boracites, Fe 3B7O13I and Cu3B7O 13Cl, manifest peaks of a gyration component g11 at each Curie point. These phenomena are entirely unintelligible from the usual concepts of the origin of ferroelectricity. Besides, the electrogyration effects of both crystals are also quite different. As has already been determined boracite crystals exhibit characteristic features of being improper ferroelectric. A phenomenological theory of improper ferroelectricity developed by Kobayashi is applied to these anomalous phenomena, and qualitative interpretations are successfully obtained.
