摘要	The low temperature dielectric and ferroelectric properties of SrTiO(3), with constant averaged A-site ionic size but different A-site disorder degrees induced by A-site cation size mismatching through the codoping of Ca and Ba, are investigated. Upon the increasing A-site disorder degree, the dielectric property shows different behaviors from individually Ca- or Ba-doped SrTiO(3) where the averaged A-site ionic size varies linearly with the doping. The transition from the quantum paraelectric state to relaxorlike ferroelectric state and eventually to normal ferroelectric state upon the increasing A-site disorder degree is revealed. The physics underlying these phenomena is discussed based on the A-site size mismatch effect. (C) 2008 American Institute of Physics.
