Abstract: Abstract Multiferroic BiFe1−xZn x O3 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.
