Large electrocaloric strength and broad electrocaloric temperature span in lead-free Ba0.85Ca0.15Ti1−xHfxO3ceramics

The electrocaloric (EC) effect of Ba 0.85 Ca 0.15 Ti 1− x Hf x O 3 (abbreviated as: BCTH x ) ceramics has been systematically investigated using an indirect method. Our results indicate that the BCTH 0.06 ceramic exhibits a sharp ferroelectric-paraelectric phase transition, around which a large EC v...
