Effect of Er-doping on structural, magnetic and dielectric properties of nano CoFe2O4

  • Mohamed Bakr MohamedEmail author


Nano Er-doped CoFe2O4 has been synthesized by a sol–gel procedure at 700 °C. The effect of Er-doping on the lattice parameter, bond lengths and bond angles has been investigated using Rietveld refinement method. Bertau method has been used to determine the distribution of different cations between tetrahedral and octahedral sites. The saturation magnetization, remanence magnetization, coercivity and anisotropy constant were reduced as the amount of Er-doping increased. The variations of dielectric characteristics with changing Er-doped amount and frequency have been examined in details.
