Abstract :
In this paper, well-dispersed 50-60 nm sized spherical BaFe (S-BaFe) particles were synthesized and characterized. The magnetic and physical properties of both nanoparticles and S-BaFe magnetic tape were discussed. The coercivity, saturation magnetization, and remanent magnetic moment of the particles were 1568 Oe, 48.6 emu/g, and 28.9 emu/g, respectively.
