Competition between Relaxation Kinetics and Heat Transfer in the Dynamics of Phase Transition Fronts Academic Article uri icon

abstract

  • The velocity of the interphase boundary motion caused by latent heat transfer at ferroelectric phase transitions is calculated. The criterion for separating of two mechanisms for the front motion - the latent heat transfer and the relaxation of the order parameter - is obtained for ferroelectrics. Electric field dynamics of interphase boundaries have been studied. The expression for the front velocity of the threshold field type is derived.
