| Abstract: | Mn-doped Bi(Mg₁/₂Ti₁/₂)–PbTiO₃disordered ferroelectric ceramics were studied under ac electric fields and a crossover from a nearly constant loss to a superlinear power-law behavior was observed.
Our results confirmed that the nearly constant loss behavior also exists in disordered ferroelectrics. The exponent of the superlinear power-law was found to be temperature dependent. Such a behavior
was related to the local movements of oxygen vacancies. |
