First paper reported the experimental measurement of various caloric effects in Pb(Mn1/3Nb2/3)O3-32PbTiO3 (PMN-PT) single crystals (Chauhan et al., 2015). This study expands upon the former one by discussing various modes for quantifying caloric effects in ferroelectric single crystals, based on different forms of Maxwell’s relations. Based on suitable combination between the dependent and driving...
Enhanced electrocaloric response has been obtained for Pb(Mn1/3Nb2/3)O3-32PbTiO3·(PMN-32PT) single crystal by the application of uniaxial compressive pre-stresses. It was observed that an improvement of the electrocaloric effect (ΔTelec=0.62K) to the tune of 200% can be obtained for an applied compressive of 28MPa against a conventional unstressed peak electrocaloric effect (ΔTelec=0.27K). Furthermore,...
