The present paper reports magnetic characterizations of spinel cobalt ferrite nanoparticles using pulse field hysteresis loop tracer. The magnetic nanoparticles with 23 nm size were produced by sol-gel auto combustion synthesis which was annealed at 500C for 4 h for better crystallinity. The obtained nanoparticles were first characterized by X-ray diffraction (XRD) technique. The XRD pattern resembles well with the reported pattern. The analysis of XRD data proves the formation of single phase cubic spinel structure of prepared nanoparticles. The XRD data was used to find a particles size, lattice constant, X-Ray density, lattice strain, dislocation density etc. All these structural parameters show good consistency with the reported values. The magnetic characterizations of the prepared cobalt ferrite nanoparticles were carried out at room temperature using pulse field hysteresis loop tracer. The important magnetic parameters such as saturation magnetization, coercivity, remenance magnetization and magneton number were deduced from M-H hysteresis curve. The obtained values of magnetic parameters show enhanced values as compare to the bulk cobalt ferrite sample. The obtained data can be useful in biomedical applications.
