The electrocaloric effect of lead-free Ba${}_{1-y}$Ca${}_y$Ti${}_{1-x}$Hf${}_x$O${}_3$ from direct and indirect measurements

David Gracia, Sara Lafuerza, Javier Blasco +1

We report on the dielectric and electrocaloric properties of Ba${}_{1-y}$Ca${}_y$Ti${}_{1-x}$Hf${}_x$O${}_3$ for compositions $0.12<x<0.18$ and $y=0.06$, as well as $x=0.15$ and $0<y<0.15$,…
