Resumo:

The influence of the structural defects on the physical properties of multiferroic systems is explored, with a particular emphasis in the dielectric response. By combining the Cole-Cole relaxation model with the Jonscher’s universal power law for AC conductivity it is possible to identify the non-Debye relaxation behaviors, providing additional insight into the microscopic mechanisms behind the observed dielectric anomalies.
