A high QM relaxor ferroelectric single crystal: Growth and characterization
Mn doped PIN-PMN-PT single crystals with diameter of 50mm have been successfully grown by the Bridgman method along >111<, >110< and >001< orientations. The effect of the acceptor dopant, Mn, on mechanical loss and other electromechanical properties was studied in comparison with pure PIN-PMN-PT single crystal under high and low electric fields. A complete set of piezoelectric, dielectric and elastic properties was derived from resonance measurements. It was demonstrated that by doping Mn, QM increases 4-5 times to 700-1000 in >001001< orientation. 2010 IEEE.
