We propose, starting from a simple energy level structure, a model for the kinetics of thermal annihilation of paramagnetic centers induced in yttria-stabilized zirconia. Previous experimental works show very different activation energies and frequency factors from sample to sample. An explanation is given taking into account the distribution of oxygen vacancy defects: the paramagnetic center annihilation depends on the number of charged oxygen vacancies and on their thermally activated rearrangements. © 1991.

Abstract

We propose, starting from a simple energy level structure, a model for the kinetics of thermal annihilation of paramagnetic centers induced in yttria-stabilized zirconia. Previous experimental works show very different activation energies and frequency factors from sample to sample. An explanation is given taking into account the distribution of oxygen vacancy defects: the paramagnetic center annihilation depends on the number of charged oxygen vacancies and on their thermally activated rearrangements. © 1991.
