Effects of B-site chemistry on BiFeO[subscript 3]-containing enhanced tetragonality systems
- UPENN
The ternary perovskite systems PbTiO{sub 3}-BiFeO{sub 3}-Bi(Mg{sub 1/2}Ti{sub 1/2})O{sub 3} and PbTiO{sub 3}-BiFeO{sub 3}-BiScO{sub 3} were investigated to clarify the relationship between the observance of multiple dielectric transitions and B-site chemistry. Multiple dielectric transitions were observed for a range of compositions in the Bi(Mg{sub 1/2}Ti{sub 1/2})O{sub 3}-containing system. A temperature-dependent diffraction study confirmed the existence of a cubic and tetragonal co-existence region at temperatures between the two transitions. No similar dielectric behavior was observed in the PbTiO{sub 3}-BiFeO{sub 3}-BiScO{sub 3} system.
