To fabricate materials with specific characteristics, the electronic structure of these materials should be comprehensively inspected against different conditions and circumstances. Circumstances such as chemical doping, valency of the ions, sites position, etc. might have significant modification to the band structure. Full potential linearized augment plane wave method (FP-LAPW) has been applied to calculate the electronic band structure of MnZnFe2O4. According to the calculations, the semiconducting parameters were predicted in terms of exchange of Mn and Zn ion substitution.
