Hard piezoelectrics based on PZT with a composition near the morphotropic phase boundary (Pb 0.94 Sr 0.06 )(Zr 0.53 Ti 0.47 )O 3 [PSZT] have been synthesized by the sol–gel method. The influence of B site aliovalent dopant Mn 3+ on the crystal structure and electrical properties has been investigated. Mn 3+ ions ( d 4 ) are found to change the crystal structure from tetragonal to rhombohedral as a result of Jahn–Teller distortion of the MnO 6 octahedra and are therefore found to impart donor characteristics to PSZT.
