Abstract

Films of a high-pressure perovskite phase, Bi(Mg_1/2Ti _1/2)O₃, were prepared on (111)c-oriented SuRuO ₃-coated (111)Pt/TiO₂/SiO₂/(100)Si substrates. The perovskite Bi(Mg_1/2Ti_1/2)O₃films had a (111) one-axis orientation, because their constituent grains were epitaxially grown on (111)_c -oriented perovskite SrRuO₃ones. The remanent polarization and piezoelectric constant measured at an applied electric field of 600 kV/cm were about 30°C/cm₂ and 40 pm/V, respectively. A remarkable phase transition was not observed from room temperature to 350°C in a (111) one-axis-oriented Bi(Mg_1/2Ti _1/2)O₃film, suggesting that the Curie temperature of this film is above 350°C.
