Abstract
Multiferroic 0.6BaTiO3-0.4NiFe2O4 dense nanoceramic composites were synthesized via a powder-in-sol precursor hybrid chemical synthesis route and a ceramic sintering process. At the measured frequency range (1 kHz?1 MHz), the relative dielectric constant is 150?1670 and the dielectric loss is 0.05?0.70. The composite ceramic showed obvious coexistence of ferroelectric and ferromagnetic phases. With the increase of temperature, the saturation ferromagnetic magnetization decreases, while the ferroelectric polarization increases.
