Abstract :
The electric field induced ferroelectric transition was studied by heat capacity measurements in relaxor Pb(Mg1/3Nb2/3)O3 (PMN) single crystal oriented in [110] direction. The modified relaxation measurements allow us to study the thermal response of sample at glassy to ferroelectric transition at isothermal condition. The thermal response of sample show a temperature anomaly at field induced transition as a consequence of the released latent heat.
