Article Preview

Ni0.5Zn0.5Fe2O4-BaTiO3 composites were prepared by calcining Ni0.5Zn0.5Fe2O4 with BaTiO3 at 1220°C for 3 h. Both μ′ and μ″ of the composites decrease rapidly, but the cut-off frequency shifts to higher level with increasing BaTiO3 content. The dielectric constant of the composites increases quickly with increasing BaTiO3 content below 50% and keeps a high and nearly unchangeable value with increasing BaTiO3 above 50%. The composites with BaTiO3 content between 20% and 40% are suitable to use for the magneto-electric devices under high applied frequency due to its high permeability and low dielectric loss.
