Resumo

The co-existence of ferroelectric and ferromagnetic properties at room temperature is very rarely observed. In multiferroics, microscopic coupling interaction between the ferroelectric and magnetic order results in the macroscopic correlation between the dielectric and magnetic properties, which is defined as magnetodielectric effect. In this paper, the magnetic behavior of the Pb(Fe1/2Nb1/2)O-3 ceramics at high temperature has been extensively studied, showing that PFN exhibits ferroelectric and ferromagnetic ordering at room temperature, converting ferroelectric PFN into a multiferroic material at this temperature.
