Structural, magnetic, electric and hyperfine behavior of a new multiferroic nanocomposite (Ni0.5Zn0.5Fe2O4)0.5(TiO2)0.5

Résumé

A new multiferroic nanocomposite resulting from a subtile mixture of Ni0.5Zn0.5Fe2O4 and TiO2 nanocrystalline grains was synthesized by bottom-up approach. The structural, nanostructural and morphological characteristics of the nanocomposite were carefully evaluated from the X-ray patterns, from fringe patterns and selected area electron diffraction (SAED) patterns obtained by High Resolution Transmission Electron Microscope. The dielectric permittivity of the NZFO-TO nanocomposite is characterized by a phase transition from the ferroelectric to paraelectric order at ∼390 K while the corresponding spectrum reveals a non-Debye type of relaxation phenomenon. It is concluded that this nanocomposite is suitable to be applied in magnetoelectric devices.
