Dr. Antonio Iacomini has published an article entitled: Large High-Temperature Piezoelectric Response of Lead-free BiFeO3–BaTiO3 Originating from Relaxor Disorder in Journal Small. The study provide evidences of a large piezoelectric response of lead-free BiFeO3-BaTiO3 (BF-BT) ceramics at elevated temperatures (d33 coefficient of 1200 pm/V at 325°C). While composed of multiple and complex contributions, the essential element of the large nonlinear and hysteretic response is the dynamics of domain walls inside hierarchical nanodomains, a feature arising due to the relaxor disorder and already observed in lead-based relaxor ferroelectrics, such as Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT).
