  • On the synthesis of nanocomposite FeNi3/C under IR heating and its application to high-density magnetic recording

    The synthesis of nanocomposite FeNi3/C based on the PAN, FeCl3 · 6H2O and NiCl2 · 6H2O, whereby the first time by the IR heating at 400 ÷ 700 ° C obtained nanocomposite FeNi3/C FeNi3 particle size of 10 to 80 nm are uniformly distributed UM. Using thermodynamic calculations based on the minimization of the Gibbs energy, confirmed the synthesis of nanocomposite FeNi3/C at T=400 ° C reduction of Fe and Ni with H2, produced during the process of carbonization of polyacrylonitrile with infrared heating. Designed as a nano material of the films can be effectively used as a carrier material for a magnetic information recording superdense. Recording density is achieved in such a carrier (85-100) Gb/dyuym2. ​
