In this study, K(Ta0.60,Nb0.40)O3/K(Ta0.40,Ta0.60)O3 heterolayered thin films were fabricated by spin coating method. KTNspecimens were manufactured according to the number of coatings and were investigated in order to apply to cooling devices. KTN heterolayered thin films showed a polycrystalline KTN X-ray patterns with some pyrochlore phase. For the six-layercoated thin film of KTN, the values of dielectric constant, dielectric loss, remanent polarization and coercive field were 1423,0.64, 19.94 μC/cm2 and 37.64 kV/cm at 28 oC. When a voltage of 330 kV/cm was applied to the 3 times coated KTN films, theelectrocaloric property was 3 oC. When a voltage of 330 kV/cm was applied, the value of the electrocaloric temperature change(ΔT of the three-layer coated thin film.
