Abstract

The anhysteretic behavior of a soft Pb(Zr,Ti)O3 was measured from 25 C to 175 C. The 


 experimental determination of the anhysteretic polarization curve, combined with classical P-E and S-

E loop measurements, allows for an experimental separation of the reversible and dissipative


 contributions to the ferroelectric behavior. This approach offers insight into the different mechanisms


 originating at the microscopic scale and the contribution to the macroscopic ferroelectric properties. It


 was found that the reversible anhysteretic susceptibility va of the unpoled material increases by 30%


 from room temperature to 150 C. On the other hand, the effect on the total susceptibility for a null


polarization vc increases only by 17% over the same temperature range. Since the difference between


va and vc reflects the dissipative contribution to the macroscopic ferroelectric behavior, this reveals


that dissipation reduces the improvement of susceptibility under increasing temperature. This work


 illustrates the benefits of separating experimentally the reversible and dissipative contributions to


 describe the ferroelectric behavior, which can serve as a basis for advanced modeling approaches.
