Frequency effect on electrical fatigue behaviour of lead zirconate titanate ceramics
Frequency effect on electrical fatigue behaviour of lead zirconate titanate ceramics
The frequency effect on the electrical fatigue behaviour of lead zirconate titanate (PZT) ceramics for a micro-actuator of hard disk drives has been investigated. The PZT sample was subjected to a bipolar electric field of ±1 kV/mm at various frequencies; 10, 50, 100 Hz. The fatigue behaviour could be attributed to the domain pinning effect and is well quantitatively analysed by using the ferroelectric logarithmic fatigue model. Significantly, it was found that fatigue degradation is more severe at low frequency loading. The frequency effect on the fatigue behaviour was explained using the viscosity concept.

Abstract
The frequency effect on the electrical fatigue behaviour of lead zirconate titanate (PZT) ceramics for a micro-actuator of hard disk drives has been investigated. The PZT sample was subjected to a bipolar electric field of ±1 kV/mm at various frequencies; 10, 50, 100 Hz. The fatigue behaviour could be attributed to the domain pinning effect and is well quantitatively analysed by using the ferroelectric logarithmic fatigue model. Significantly, it was found that fatigue degradation is more severe at low frequency loading. The frequency effect on the fatigue behaviour was explained using the viscosity concept.
