Phenomenological description of depoling current in Pb0.99Nb0.02(Zr0.95Ti0.05)0.98O3 ferroelectric ceramics under shock wave compression: Relaxation model

Abstract: By assuming a relaxation process for depolarization associated with the ferroelectric (FE) to antiferroelectric (AFE) phase transition in Pb0.99Nb0.02(Zr0.95Ti0.05)0.98O3 ferroelectric ceramics under shock wave compression, we build a new model for the depoling current, which is different from both the traditional constant current source (CCS) model and the phase transition kinetics (PTK) model. The characteristic relaxation time and new-equilibrated polarization are dependent on both the shock pressure and el… Show more

“…19 Shock depoling studies of various polarization states have been thoroughly investigated, including configurations in the unpoled state, [19][20][21][22][23][24][25][26][27] the axially poled state, 24,26,[28][29][30][31][32][33] and the transversely poled state. 21,[24][25][26]32,34,50 The effect of electrical boundary conditions has also been explored for the uniaxial strain regime, including short circuit 21,[24][25][26]31,36,35 and high field 21,23,25,26,32,34,36,37 configurations. Capacitive loads have also been considered.…”
