Production of Zinc-Doped Yttrium Ferrite Nanopowders by the Sol–Gel Method
Zinc-doped yttrium orthoferrite nanocrystals having the perovskite structure were prepared by coprecipitation of yttrium, zinc, and iron hydroxides. The limiting zinc doping level of the yttrium ferrite to yield a ZnFe 2 O 4 spinel second phase was determined. The yttrium orthoferrite particle size...
