摘要
Dielectric properties of BaTiO3 (BT) doped with Nb2O5, Co2O3, CeO2 and Mn(NO3)(2) under DC bias field were investigated. It was found that Mn could improve DC bias characteristics of the system. Dielectric constant decreased with the increase of DC bias in Mn-free samples. The curves of dielectric constant vs. DC bias showed a stable or increasing tendency in higher Mn-doping BaTiO3. The characteristic of stable or increasing dielectric constant vs. DC bias is very promising for applications of the system in many electronic devices under operating voltages.
