- 論文の詳細を見る
Effects of a small deviation l>(Fe. ,0.) from the stoichiometric Fe.0. on the dielec-tric and conducting properties have been investigated below 80 K. The l? was con-trotted by annealing {100} thin plates at l300'C in CO-CO.-Ar mixing gas. Thedielectric constant shows pronounced relaxational anomalies at about 10 K and 40 K,and the dielectric behavior is very much dependent on 6. The ac conductivity o..shows a frequency dispersion, o..cf- co' (.s'< 1 ), suggesting that an impurity conductionmechanism predominates in low temperatures (7'< 60 K). The electrical properties arediscussed by considering electric dipoles formed by ionized defects.
