Dielectric relaxation in (x)Mn0.4Zn0.6Fe2O4–(1–x)PbZr0.53Ti0.47O3 magnetoelectric composites near the ferroelectric phase transition
Temperature dependences of the dielectric losses in (x)Mn0.4Zn0.6Fe2O4–(1–x)PbZr0.53Ti0.47O3 magnetoelectric composites are studied at frequencies of 200 to 5000 Hz near the ferroelectric phase transition. A relaxation peak of the dielectric losses is revealed that, according to experiments, is mainly due to the mechanism of a new phase emerging in a substance and the kinetics of interphase boundaries.
