| Research Abstract |
Four states are tried to realize using Bi-based ferroelectric films having more than 20% self-strain. Epitaxial films having both of about 7 and 22% tetragonlity were successfully grown by changing the x values in [(2/3)[Bi((Zn1-xMgx)1/2Ti1/2)O3]-(1/3)[BiFeO3]. However,their tetragonality did not drastically change up to 800 degree. Epitaxial Bi((ZnxMg1-x)1/2Ti1/2)O3 films having about 22% tetragonlity were also grown, but smaller one cannot be obtained.
