Abstract
The spectra of the dielectrical constant and dielectrical loss in three nan ostructured alpha-Fe2O3 samples at different annealed temperatures are meas ured by using sc LRC method. The relaxation times of polarization and the c onductance are calculated by means of the Debye mechanism and the interface effects in two kinds of polarization processes with two different relaxati on times are proposed.
