Abstract

Crystals of Mn-doped Pb(Zn_1/3Nb_2/3)O₃ (PZN) were grown by a flux technique. The dielectric and piezoelectric properties were investigated for 〈001〉 oriented crystals. Mn-substitution resulted in combinatory hardening and softening effects. Under high power resonant drive, the mechanical quality factor (Q_m) and vibration velocity showed a considerable improvement, compared to the unmodified PZN crystals. Also, the longitudinal piezoelectric coefficient (d₃₃) was increased by Mn substitution. The combinatory effect is explained on the basis of mixed valence states of Mn.
