Electrical properties of nickel ferrite.

Per mole rather than the previously accepted values of about 46 and 39 kcal. Nickel ferrite nife 2 o 4 is one of the most important spinel ferrites that have been studied. The nickel ferrite nanopowder was synthesized by sol gel method. The structural properties of all the thin films were studied by using bruker d8 advance x ray diffractometer using cu kα radiation in the 2θ range of 20 80.

In order to investigate structural optical electrical surface morphology and magnetic properties of prepared al 3 doped nickel ferrite thin film different characterization techniques were used. Physical and electrical properties of a nickel ferrite as affected by compositional changes physical and electrical properties of a nickel ferrite as affected by compositional changes mum s. 1 chemistry department faculty of science benha university benha egypt. Discussion on electrical properties of ferrites is generally explained by carrier hopping model or band structure.

Electrical conductivity optical properties abstract polyaniline nife 2o 4 nanocomposites pani nife 2o 4 with different contents of nife 2o 4 2 5 5 and 50 wt were prepared via in situ chemical oxidation polymerization while the nanoparticles nickel ferrite were synthesized by sol gel method. 2 physics department faculty of science benha university benha egypt. Per mole respectively. An appropriate amounts of nickel nitrate ni no 3 2 6h 2 o and ferric nitrate fe no 3 3 9h 2 o were mixed together with citric acid and polyethylene glycol peg with 1 2 4 44 8 88 molar ratio of ni no 3 2 6h 2 o fe no 3 3 9h 2 o citric acid and peg.

Khairy m 1 gouda me 2. Although there are few reports on different properties of ni zn ferrite a systematic investigation about electrical properties is lacking so there is a need for investigation of electrical properties on ni zn ferrite to understand. Gouda journal journal of advanced research year 2015 volume 6 pages 555 562. Stoichiometric nife 2 o 4 considers as n type semicoductor.

The prepared samples were. Nickel was first discovered by alex constedt in 1751. It exhibits different kinds of magnetic properties such as paramagnetic superparamagnetic or ferrimagnetic behavior depending on the particle size and shape. Up to the present the only systematic investigation published on the semiconducting behaviour of ferrites is a study of cobalt ferrite cofe 2 o 4 by jonker 1.

Electrical and optical properties of nickel ferrite polyaniline nanocomposite. In the case of nickel ferrite it is known that these properties are closely. 6 likely to be of the order of 0 to 10 kcal.
