Abstract
A crystalline perovskite crystalline composite paraelectric material includes nano-regions containing rich Nanions dispersed in a nano-grain sized matrix of crystalline oxide perovskite material, wherein (ABO)-(ABON). A represents a divalent element, B represents a tetravalent element, γ satisfies 0.005≦γ≦1.0, 1-α satisfies 0.05≦1-α≦0.9, and 1-α is an area ratio between the regions containing rich Nanions and the matrix of remaining oxide perovskite material.
