Structure–Property Relationship in Mn-Doped (Pb0.94Sr0.06)(Zr0.53Ti0.47)O3
Hard piezoelectrics based on PZT with a composition near the morphotropic phase boundary (Pb0.94Sr0.06)(Zr0.53Ti0.47)O3 [PSZT] have been synthesized by the sol–gel method. The influence of B site aliovalent dopant Mn3+ on the crystal structure and electrical properties has been investigated. Mn3+ions (d4) are found to change the crystal structure from tetragonal to rhombohedral as a result of Jahn–Teller distortion of the MnO6 octahedra and are therefore found to impart donor characteristics to PSZT.
