De pendence of magnet ic properties of cob alt ferrite nanoparticles on b all m illing time

Cobalt ferrite nanoparticles (CoFe۲O۴), including magnetic m aterials have spinel f errite struct ure show interesting pro perties [۱]. CoFe۲O۴ str ucture is a ferrimagnet oxide with p artial inverse spinel str ucture that its degree of inversion depends on the preparation method and heat treatment [۲]. This kind o f ferrite was an interesting matter f or research [۱,۲,۳,۴]. Because of high saturation magnetization, field co ercivity, hi gh physical and chemical stability cobalt ferrite is attracti ve for rese archers[۴]. It has many applicatio ns including ferrofluid , the recording magnetic and targeted drug deli very [۴]. In this work, c obalt ferrite nanoparticl es by comb ustion metho d were gen erated and th en were ball milled on two different times.
