摘要：

We report that "ferroelectric relaxor" behavior is induced by doping Bi in quantum paraelectric SrTiO3, and doping Ce in typical ferroelectric BaTiO3. The present results show that the "ferroelectric relaxor" state may exist no matter whether the matrix is ferroelectric or paraelectric, however, the relaxer behavior is the dynamic response of the polar clusters induced in the system.
