Abstract
Lead doped nickel ferrite Ni1-xPbxFe2O4 (x = 0.0 to 1.0) nanoparticles have been successfully prepared via co-precipitation method. The structural and magnetic properties investigated by XRD, FTIR, TEM, and VSM. XRD confirmed the formation of cubic spinel structure. Particle size evaluated using Debye Scherrer formula was found to be in the range 30–50 nm. In FTIR spectra, two fundamental absorption bands at around 620 cm−1 and 500 cm−1 observed whereas the characteristic of M-O vibrations. TEM image shows that the particles are agglomerated and spherical shape. Magnetic parameters of coercivity, remenence, squareness ratio, and anisotropy constant values decrease.
