Abstract

Multiferroic BiFe_1−xZn_xO₃ ceramics were prepared by solution combustion method. Their structure, magnetoelectric, dielectric, magnetic, thermal characteristics were studied. The magnetic M(T) and heat capacity C_p(T) measurements demonstrate an antiferromagnetic to paramagnetic phase transition (T_N) around 635 K. The anomaly on the temperature dependence of the dielectric constant near T_N was observed, which could be induced by the magnetoelectric coupling between electric and magnetic ordering. The magnetoelectric behavior was also confirmed by the linear relation between Δε and M², which is in the agreement of the Ginzburg-Landau theory for the second-order phase transition.
