Abstract

Ferroelectric and piezoelectric properties of layered Lu2Fe2.1Mn0.9O7ceramic have been investigated by temperature-dependent piezoresponse force microcopy (PFM) and dielectric measurements. The PFM results illustrate the existence of piezoelectric properties and ferroelectric phase transition temperature of about 90 °C at which the piezoelectricity vanishes. This transition temperature is manifested by the appearance of a shoulder at about 90 °C in the temperature-dependent dielectric curve of the poled sample. A macro-to-micro domain transition is proposed to explain this ferroelectric phase transition. Besides, the ferroelectric properties of the Lu2Fe2.1Mn0.9O7ceramic are further demonstrated by the polarization-electric field hysteresis (P-E) loop measurement.
