Achieving high piezoelectric response and elevated Curie temperature in Sm-modified PMN–PH–PT ceramics: A full-matrix characterization

Abstract Pb-based ferroelectric ceramics face a fundamental trade-off between high piezoelectric response (d33) and low Curie temperature (Tc). Here, we demonstrate that combining Sm-doping with a high-Tc PbHfO3 (PH)-based ternary matrix can effectively shift this balance. A seri...
