    The influence of the particle size on magnetic behaviors of nickel
    oxide nanoparticles (NiO NPs) was reported. NiO NPs with a uniform particle
    size were synthesized via a facile sol-gel method, and various sizes of NiO NPs
    (11, to 49 nm) were achieved by calcination at various temperatures (400, to 700
    °C). X-ray diffraction (XRD) analysis revealed that increasing the calcination
    temperature increased the crystallite size. TEM observations and XRD analysis
    were used to determine the particle size of the NiO NPs. The field emission
    scanning electron microscopy (FESEM) and transmission electron microscopy
    (TEM) images showed flake-like morphologies, which consisted of
    interconnected nanoparticles with a porous channel. The magnetic properties of
    NiO NPs with different size were studied using vibrating sample magnetometer
    (VSM). The results suggested that the particle size plays an important role in
    magnetic property of NiO nanoparticles.
