Effect of doping and sintering in structure and magnetic properties of the diluted magnetic semiconductor ZnO:Ni
Abstract This work aimed to study a sintered Ni-doped ZnO dilute magnetic semiconductor synthesized by means of a combustion reaction and to evaluate the effect of doping and sintering in the band gap and magnetic properties of the material. X-ray diffraction showed the formation of the ZnO semicond...
