摘要：
The effect of La 3+ and Zn 2+ codoping on the microstructure and dielectric properties in the 0.9Pb(Mg 1/3 Nb 2/3 )O 3 -0.1 PT ceramics was studied. Raman spectroscopy was used to study the small changes of ordering degree. The relative dielectric constant change with DC bias field was measured. When 2 mol. % La 3+ and 3 mol. % Zn 2+ was codoped, two dielectric peaks were observed in the temperature dependence of the dielectric constant. The maximal relative dielectric constant change decreased from 70.46% to 23.15% at 10 kHz (0 greater than or similar to 1000 V/mm). The La 3+ and Zn 2+ codoping markedly increased the temperature and electric field stability of 0.9Pb(Mg 1/3 Nb 2/3 )O 3 -0.1PT ceramics.
