Abstract
Oxidation temperatures and times of Fe3O4 to produce (Co,Zn)-doped gam ma-Fe2O3 particles were examined in this study to relate these two par ameters to void, particle sizer saturation magnetization, coercivity, and squareness. The effect of Zn/Co ratio on magnetization and coerciv ity of the particles was also studied. The partial substitution of Zn for Co in Co-gamma-Fe2O3 increased the sigma value and environmental s tability, but decreased the H-i(c) and the squareness of gamma-Fe2O3.
