Abstract

Novel perovskite-type oxide (Lag_0.54(9)Ag_0.33(1))TiO_2.93(9) was synthesized by the conventional solid state reaction method. The perovskite-phase was found to have a simple cubic symmetry with the lattice parameter a = 3.8799(6) A. Using the adjusted solution of the sulfuric acid added some ammonium sulfates, the sample can be dissolved. The analysis of ICP was carried out to determine the elemental ratio of sample. At low temperature, (La_0.54(9)Ag_0.33(1))TiO_{2. 98(9)} shows a quantum paraelectric behavior.
