Abstract

This study reports the synthesis and characterization of nanocrystalline Ni0.5Co0.2Zn0.3BixFe2-xO4 x varis by 0.0, 0.025, 0.050, 0.075, 0.100 ferrites synthesized via the sol-gel auto combustion method.The low coercivity values 23.68 to 87.71 Oe are observed,classifying the investigated materials as soft ferromagnetic.The increased magnetic anisotropy K through Bi3+ doping indicates tunable stability in magnetic orientations,making them suitable for multifunctional applications.
