Electrocaloric Cooling Cycles in Lead Scandium Tantalate with True Regeneration via Field Variation

There is growing interest in heat pumps based on materials that show thermal changes when phase transitions are driven by changes of electric, magnetic, or stress field. Importantly, regeneration permits sinks and loads to be thermally separated by many times the changes of temperature that can aris...
