    Abstract

    We studied the dynamics of two-phase coexistence in perovskite manganite R MnO3 (R =rare earth) by means of dynamical specific heat measurement. We found that specific heat exhibits a Debye-type frequency dependence around the transition temperature between two different magnetic phases, which can be attributed to the relaxational domain motion between the two phases. We also found that relaxation time (τ) systematically varies with the change of R as well as with an applied magnetic field, and dispersion frequency (1/τ) divergently increases as the system approaches the critical point of the magnetic phases.
