Abstract
The temperature dependence of the energy loss of 624-keV electrons in ferroelectric barium titanate (BaTiO3) and triglycine sulfate [(CH2NH2COOH)3 H2SO4] has been studied with the use of a single-gap magnetic spectrometer. The present measurements confirm the anomalous increase in energy loss of electrons near the Curie temperature TC and indicate its dependence on (a) the magnitude of the dielectric anomaly at TC, (b) the effect of a dc electric field larger than the coercive field, and (c) the application of an alternating electric field. Probable mechanisms for the origin of the observed phenomenon are discussed.
