摘要	We prepare a series of polycrystalline Sr(0.9-x)Ba(0.1)Ca(x)TiO(3) (SBCT) with relatively low Ba- and Ca-doping levels, and their microstructural, ferroelectric, dielectric, and lattice dynamic properties are investigated. It is surprisingly found that a proper Ca(2+) doping, which usually favors the antiferroelectric state in SrTiO(3), can remarkably enhance the ferroelectricity of SBCT. The coupling and competition between the ferroelectric state induced by Ba(2+) doping and antiferroelectric state induced by Ca(2+) doping lead to a sequence of multipolarized states, such as the enhanced polarization state, the cooperative polarization state, and the antiferroelectric state.
