摘要	The measurements of electric capacities and dielectric loss angles for nanocrystalline gamma-Fe2O3 under air and vacuum atmospheres have been conducted by using ac LRC method, and the conductivity and the polarization relaxation time have also been calculated from the frequency spectra of real and imaginary parts of the dielectric constants. The anomalous dielectric behavior implies the existence of two kinds of polarization mechanisms with different relaxation times, which are caused by the defects and the dangling bonds in the interlaces, respectively. The experimental and calculated results indicated that the polarization loss and thf! conductance loss are dominant in air atmosphere and vacuum, respectively.
