Orientated ferromagnetic Ni0.89Fe0.11 nanoparticle/polymer nanofibres were made by electrospinning a solution containing iron(III) nitrate nonahydrate, nickel(II) acetate tetrahydrate, polyvinylpyrrolidone, and acetic acid in methanol thermally processed Ar then 95%Ar:5%H2 up to 620 °C. There was distribution nanofibre widths after with wider (average width 440 nm) some thinner 120 nanofibres. ...

The nano-crystalline nickel-zinc ferrite was prepared via chemical synthesis. Zinc nitrate, nickel nitrate, iron nitrate hydrate, citric acid and ethylene glycol were used as precursor materials. Crystallization behavior of the precursor was studied by X-ray diffraction (XRD). Nanoparticle phases can change amorphous to spinel ferrite depending on the calcination temperature and crystallite siz...
