000163260 5203_ $$aThis study explores the effects of Cu substitution on the structural, morphological, and magnetic properties of nickel ferrite nanoparticles, Ni1-xCuxFe2O4, where x = 0.25, 0.50, and 0.75. SEM analysis revealed that the particles are spherical with an average size of 7 nm. The Nickel-Copper ferrite nanoparticles presented a characteristic XRD diffraction corresponding to the cubic spinel structure of the Fd3m space group, with no secondary phases formed due to Cu substitution. The crystal sizes of Ni-Cu spinel ferrites were calculated via Debye-Scherrer formula to be between 44.9 and 52 nm. FT-IR results indicated an increase in the force constants of octahedral and tetrahedral bonds with higher Cu content, as evidenced by the main vibration bands. M-H curves displayed S-shaped behavior, suggesting that Cu substitution does not cause drastic changes in magnetic properties. The coercivity field (Hc), saturation magnetization (MS), and remanent magnetization (Mr) values ranged between 13.54 and 6.14 Oe, 48.8–52.7 emu/g, and 0.57–1.14 emu/g, respectively. Blood compatibility experiments showed that the Ni0.25Cu0.75Fe2O4 composition exhibited the highest blood compatibility at low concentrations among the studied samples.
