title = "Effect of the grain size on magnetic properties of nanocrystalline CoFe2O4 ferrite",
abstract = "Nanocrystalline CoFe2O4 ferrite have been synthesized by a spraying-coprecipitation method. X-ray diffraction (XRD) and Transmission electron microscope (TEM) confirmed the formation of single-phase CoFe 2O4 ferrite nanoparticles in the range 10 nm ∼ 100 nm depending on the calcining temperature. The magnetic measurements show that specific saturation magnetization of nanocrystalline CoFe2O 4 ferrite increases from 36.1 A·m2·kg -1 to 88.6 A·m2·kg-1 as grain size increases from 12 nm to 98 nm. The coercivity shows a peak with grain size, peaking at around 43 nm. The magnetic behaviour of nanocrystalline CoFe 2O4 ferrite might be attributed to the effects of surface and random anisotropy.",
