Abstract

The dielectric constant and loss of perovskite DyMn _1-xFe _xO ₃ 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 f ₀ and the activation energy E _α 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 E _α. © 2012 American Institute of Physics.
