Tetragonal tungsten bronze oxides with the general formula(A1)p(A2)6-p(B1)8-p(B2)2+pO30(p = 3,4,5)are parts of the major dielectric family next to perovskit
Giant electrostrains of up to~0.4%have attracted lots of attention in recent years in some perovskite-structured relaxor ferroelectric ceramics such as(Bi1/
The role of mixed-valence structure in colossal-dielectric-constant(CDC)behavior has been investigated in LaFeO3 ceramics by tuning the ratio of Fe2+/Fe3+th
