Extended X-ray absorption fine structure and X-ray diffraction studies of Mn-doped PZN-PZT ceramics
In this work, the selected compositions of a combination between perovskite piezoelectric ceramics lead zinc niobate (PZN) and lead zirconate titanate (PZT), close to the morphotropic phase boundary (MPB) i.e. the 0.2PZN-0.8PZT, doped with MnO2concentrations of 0.0-0.9 wt% were fabricated by a simpl...
