Cation Engineering in Spinel M₀.₄Fe₂.₆O₄ (M = Co, Mn, Zn) Ferrofluids: Correlating Crystal Structure, Magnetic properties, and Rheological Response
Cation substitution provides an effective route for tailoring the magnetic and rheological properties of spinel ferrite ferrofluids. In this work, Zn₀.₄Fe₂.₆O₄ (ZFO), Mn₀.₄Fe₂.₆O₄ (MFO), and Co₀.₄Fe₂.₆O₄ (CFO) nanoparticles were synthesized under identical conditions and dispersed in kerosene to investigate the influen...
