A series of BaTiO 3 –Ni 0.55 Zn 0.45 Fe 2.03 O 4 composites are synthesized. The composites exhibit excellent dielectric and magnetic properties in the neighborhood of the percolation threshold—a high dielectric constant that is nearly temperature and frequency independent (see figure)–and considerable initial permeability with excellent frequency stability, and may be useful as a high‐performance multifunction ceramic composite.
