Nk. Yushin et Ep. Smirnova, QUASI-STATIC SUSCEPTIBILITY DERIVED FROM FIELD-INDUCED STRAIN IN ELECTROSTRICTIVE CERAMICS, Ferroelectrics. Letters section, 21(3-4), 1996, pp. 101-110
Quasi-Static (QS) susceptibility was derived from field induced strain
in ferroelectric ceramics with Diffuse Phase Transition (DPT). This Q
S susceptibility was observed to be determined by the field amplitude,
the smooth dependence epsilon(E) being on the strong fields and the s
harp falling epsilon(E) being on the small fields.
