Abstract:
Multiferroic composites of ( x )NiFe 2 O 4 + (1- x )BaTiO 3 with x = 0.2, 0.3 and 0.4 and ( x )CoFe 2 O 4 + (1- x )BaTiO 3 with x = 0.2, and 0.4 have been synthesized by mixing NiFe 2 O 4 (CoFe 2 O 4 ) spinel and BaTiO 3 piezoelectric. Distribution of Ni (Co) ions on 8 a and 16 d positions of spinel lattice (space group F d -3 m ) is determined by neutron powder diffraction. Wave vector of magnetic structure of the spinel is k = 0. The dielectric permittivity of the composites was measured for the frequency range 10 2 – 10 5 Hz. At low frequencies the dielectric permittivity decreased from ~940 for x = 0.2 to ~360 for 0.4.
