Mn modified 0.26Pb(In1/2Nb1/2)O-3-0.42Pb(Mg1/3Nb2/3)O-3-0.32PbTiO(3) (PIN-PMN-PT:Mn) single crystals with orthorhombic perovskite crystal structure were polarized along [011] direction, resulting in the single domain state 1O. The complete set of material constants was determined using the combined resonance and ultrasonic methods. The thickness shear piezoelectric coefficient d(15) and electromechanical coupling factor k(15) were found to be on the order of 3100 pC/N and 94%, respectively, much higher than longitudinal d(33) similar to 270 pC/N and k(33) similar to 70%. Using the single domain data, the rotated value of d(33)* along [001] direction was found to be 1230 pC/N, in agreement with the experimentally determined d(33) value of 1370 pC/N, conferring extrinsic contributions being about 10%, which was also confirmed using the Rayleigh analysis. In addition, the mechanical quality factors Q(m) were evaluated for different 1O vibration modes, where the longitudinal Q(m) was found to be similar to 1200, much higher than the value for 4O crystals, similar to 300.
