Abstract


  • The dielectric constant and loss of perovskite DyMn1xFexO3 samples show strong dispersion in

    various frequencies, which is indicative of relaxation. The activation energies were obtained

    through Arrhenius law fitting and range from 0.213 eV to 0.385 eV. The Fe content dependence of

    the characteristic frequency f0 and the activation energy Ea shows two transitions that are well

    consistent with the change in orbital ordering. Meanwhile, different magnetic orderings could

    affect the relaxation and induce the change in Ea
