Dielectric properties and phase transition mechanisms in Sr1-xBaxTiO3 solid solution at low doping concentration
Dielectric properties of Sr1-xBaxTiO3 (x less than or equal to 0.30) solid solution were studied by means of dielectric constant, DE loop, pyroelectricity measurements, and so on. A quantum paraelectric to quantum ferroelectric transition was observed for samples with a small amount of Ba content ( 0.005 less than or equal to x less than or equal to 0.10). Possible phase transition mechanisms are discussed.
