Migration polarization study in alumina phosphate glasses by the ionic thermocurrent technique

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Ionic thermostimulated currents (ITC) of several alumina phosphate glasses are measured and analysed in terms of distributed polarizations. The relaxation spectrum analysis yields the value of the activation energy for reorientation of complexes 0·73 eV for all subpolarizations distributed in frequency factor with the most probable value ∼1·25×1012 sec−1. The ITC experimental results are confronted with the dc conductivity measurements within the framework of the used model of alkali ion migration in glass.
