Dielectric Relaxation in Crystalline V2O5.
Abstract
The real part of the dielectric constant in crystalline V2O5 has been measured in the temperature range 80K to 200K. It rises from about 5, at low temperature, to about 9 in a narrow temperature range which depends upon frequency. The ac conductivity exceeds the dc conductivity by a measurable amount at low temperature, because of the contribution of relaxation. The crystal behaves approximately as a Debye dielectric. The relaxation time was found as a function of temperature. Two models for dipolar centers are proposed and discussed. (Author)
