摘要：
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 ferro-electric to paraelectric order at similar to 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.
