Query: Quasi-indirect measurement of electrocaloric temperature change in
  PbSc0.5Ta0.5O3 via comparison of adiabatic and isothermal electrical
  polarization data   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 slow variation of electric field, and
adiabatic changes of electrical polarization due to 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 300 - 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 future.
