Abstract

The magnetic, electric and optical properties of pure and ion doped CuCr

_{2}

O

_{4}

- bulk and nanoparticles are investigated theoretically. The magnetization

M_{s}

and the band gap

E_{g}

decrease with increasing particle size. By Co ion doping

M_{s}

and the polarization P show a maximum whereas by Pr ion doping they decrease with increasing the doping concentration. The dielectric constant decreases with enhancing Pr dopants. It is shown that the difference between the doping and host ions radii leads to appearing of a compressive or tensile strain and to different exchange interaction constants in the doped state.

E_{g}

decreases by Co doping, whereas it increases by Pr doping.

Keywords: CuCr₂O₄ nanoparticles; ion doping; magnetization; polarization; band gap energy
