TY  - JOUR
AB - Electrically driven adiabatic changes of temperature are identified in the archetypal electrocaloric material PbSc0.5Ta0.5O3 by comparing isothermal changes of electrical polarization due to the slow variation of electric field and adiabatic changes of electrical polarization due to the fast variation of electric field. By obtaining isothermal (adiabatic) electrical polarization data at measurement (starting) temperatures separated by <0.4 K, we identify a maximum temperature change of ∼2 K due to a maximum field change of 26 kV cm−1 for starting temperatures in the range of 300 K–315 K. These quasi-indirect measurements combine with their direct, indirect, and quasi-direct counterparts to complete the set and could find routine use in the future.
