Abstract
A manganese-doped BaTiO3 was investigated with regard to the degradation of resistivity under a high d.c. electric field. Degradation was measured as a function of time, composition and temperature, using an electric field of 3 Vμm−1. The activation energy of the process was found to be 1.13 eV. to clarify the mechanismI againstU characteristics andI againstT graphs of new, degraded and relaxed samples were studied. Electron paramagnetic resonance and potential measurements were found to be useful in describing the degradation. Finally, a brief model is put forward to account for the observed phenomena. It is based on an injection of oxygen vacancies from the anode, which is accompanied by a reduction of manganese in the lattice.
