Abstract
The dielectric properties and positron annihilation lifetime spectra of the ceramics with the nominal composition Sr1−xLaxTiO3 (0≤x≤0.06) were measured. The dielectric properties and relaxation behaviors, which varied obviously with lanthanum content, were explained by a charge compensation model. The defect structure of the materials was further discussed and the above model proved to be reasonable by the positron annihilation study.This publication has 8 references indexed in Scilit:
