Abstract :
Exchange constants and band gap is predicted numerically for artificial nickel ferrite since they directly affect the magnetization and conductivity. These fundamental issues are addressed using density functional calculations to study the magnetic properties and the density of states of the material. The magnetization is deduced from the local magnetic moments calculated from the Mulliken population analysis.
