PST thin films for electrocaloric coolers
Relaxor behaviour in a thin film of partially ordered PbSc 0.5 Ta 0.5 O 3 (PST) was confirmed via slim P – E loops and the frequency dependence of the temperature at which the dielectric constant is maximum. Indirect measurements of the electrocaloric effect suggest that removing a field of 774 kV c...
