N2 - The dielectric, piezoelectric, and ferroelectric properties of Mn-doped and undoped yPb(In1/2Nb1/2)O3-(1−x−y)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PIN-PMN-PT) ternary ceramics with morphotropic phase boundary composition have been investigated. Mn-doped PIN-PMN-PT ceramics show obvious hardening characteristics. With 2 mol% Mn doping the mechanical quality factor Qm can be increased to as high as 2000, while the electromechanical coupling factor (kp=57%) is still comparable to that of the undoped counterpart. The internal bias field Ei was analyzed and calculated based on the P-E hysteresis loops for the Mn-doped PIN-PMN-PT ceramic. The relatively high Curie temperature, very high Qm, and low dielectric loss make the Mn-doped PIN-PMN-PT ceramics good candidates for high power and high temperature electromechanical device applications.
