Abstract
The dielectric anomalies occurring around 8, 18, 30, and 65 K (at 100 Hz) i n Bi:SrTiO3 have been observed. They are frequency-dispersive and their rel axation rate follows the Arrhenius law. The physical nature of the dielectr ic anomalies around 18 and 30 K has been the focus of the study, and a poss ible explanation is given. (C) 1999 Elsevier Science Ltd. All rights reserv ed.
