摘要：
This study reports the processing and characterization of Pb0.96Sm0.025[Mg1/3Nb2/3](0.70)Ti0.30O3 (Sm-PMN-PT) polycrystalline ceramics for solid-state refrigeration technologies. The composition illustrated maximum polarization of nearly 40 mu C/cm(2) at 293 K for an applied electric field of 17.5 kV/cm and piezoelectric coefficients d(33) similar to 146 pm/V under application of 10 kV/cm. It also showed a pyroelectric coefficient-4610 mu C/m(2)/K-1 in the temperature range 340 - 370 K. In contrast to parent PMN-PT, the composition showed above room-temperature ferroelectric transition offering an appealing change in polarisation and better suitability from a device view-point. Due to this, the present study explored Sm-PMN-PT for an electrocaloric effect (ECE) using Maxwell re-lations. Our calculations suggest a maximum ECE entropy (|Delta S|) and temperature (|Delta T|) changes of 0.55 J/Kg.K and 0.7 K for a broad temperature range of 20 K (390-410 K), respectively.
