Title: Structural, morphological and magnetic study of (Bi{sub 0.1}Fe{sub 0.1}O{sub 3}) - (Ni{sub 0.1}Fe{sub 2(0.1)}O{sub 4}) nanocomposite

Multiferroic nanocomposite of (Bi{sub 0.1}Fe{sub 0.1}O{sub 3}) - (Ni{sub 0.1}Fe{sub 2(0.1)}O{sub 4}) was prepared by sol gel technique and characterized by X-ray diffraction, transmission electron microscopy, superconducting quantum interference device. X-ray diffraction confirmed the formation of desired crystallographic phase of the composite. The average particle size found to be 13.97nm. The transmission electron microscopy depicts the presence of the polycrystalline nanoparticles. In order to investigate the magnetic behavior superconducting quantum interference device was used. The sample was analyzed by increasing the magnetic field up to 25kOe and magnetization was found to be 16.8emu/g, which is optimum for the technological applications. The magnetic properties in such composite result as determined both by the ferrite concentration and properties and by the degree of connectivity of the two phases. The appropriate combination of two phases gives rise to higher magnetization.
