PIEZOELECTRIC THIN FILM, PIEZOELECTRIC ACTUATOR, INKJET HEAD, INKJET PRINTER, AND METHOD FOR MANUFACTURING PIEZOELECTRIC ACTUATOR
Abstract: A piezoelectric thin film obtained by adding a donor element to lead zirconate titanate. In the above piezoelectric thin film, the ratio of lead in relation to the total of zirconium and titanium is 105% or higher in terms of the molar ratio. |Ec(+)|/|Ec(-)| is 0.5 to 1.5, where Ec(+) and Ec(-) respectively represent the positive and negative coercive electric fields in polarization-electric field hysteresis.
