ABSTRACT
We analysed the imaginary part of frequency dependent dielectric constant ∈' (ω) of amorphous LiNbO[sub 3] at temperatures below the crystallization using the Mode coupling theory(MCT). We found that ion transportation behavior in amorphous LiNbO[sub 3]can be explained well by the MCT α relaxation predictions. We observed the α relaxation scaling in ∈' (ω) and as a result of which the a relaxation stretched exponent βDC was temperature independent with β[sub DC ... 0.6.
