Defect-engineered BT-based ceramics: correlating phase coexistence, electrocaloric response and energy storage performance via Fe and Mn substitution

Year: 2026

Type: article

Abstract: for the Mn-doped ceramic. The good agreement between direct and indirect measurements confirms the reliability of the obtained results. While Mn substitution enhances electrocaloric strength, Fe doping ensures a more stable and broader thermal response. These findings demonstrate that dopant-controlled defect chemistry and phase coexistence provide an effective strategy for optimizing multifunctional properties in BCTSZ ceramics, making them promising candidates for dielectric capacitors and solid-state electrocaloric cooling operating under moderate electric fields.
