One pot synthesis of nickel ferrite-graphitic layers nanocomposite with inverted magnetic hysteresis

For the first time, we report the synthesis of nickel ferrite-graphitic layers nanocomposite (C-NiFe2O4) via a straightforward approach using iron-nickel cyanide powder (Fe[Ni(CN)4]·3H2O). Firstly, iron-nickel cyanide powder was prepared by mixing equal molar amount of iron salt and potassium tetracyanonickelate (II) hydrate. Secondly, the as-synthesized iron-nickel cyanide powder was thermally treated in air at a temperature as low as 400 °C....
