In (CoFe2O4 ) nanoparticles are widely utilized in electronics and biomedicine. Undoped and Al doped cobalt ferrite nanoparticles were manufactured through cost operative co-precipitation process. X-ray diffraction analysis (XRD) showed single cubic phase of cobalt ferrite and a constant reduction of the lattice constant upon aluminum content. The scanning electron microscope (SEM) analysis acquired the uniform scale dispersion of the well crystallized grains. Optical band gaps (Eg ) were observed utilizing Transmittance spectra. Photo Luminescence (PL) studies displayed wide emission peak of energy 3.45 eV, credited to the charge recombination that is attributable to deep traps and lattice faults of confined surface states. Raman analysis proved the stretching of metal oxygen, active vibration of metal cation and bending vibrations. The vibrating sample magnetometry (VSM) analysis showed the coercivity (Hc ) and the saturation magnetization (Ms ) decline upon an rise in aluminum content. Cytotoxicity studies proved so as to the anticancer attributes of cobalt ferrite nanoparticles..

Nanomaterials of cobalt ferrite (CoFe2O4) doped with zinc have been synthesized by co-precipitation using KOH solution of 10-4 M as a precipitant. The effect of zinc contents and calcination temperature on the structure and magnetic properties of Co1-xZnxFe2O4 were studied. The parameters of the crystalline cubic lattice (a ~ 8.4 Å) and the crystalline size (d = 20–30 nm) increased with increasing the calcination temperature and zinc content in the samples. However, the remanent magnetization, saturation magnetization, coercive force and M at the maximum field decreased with increasing the zinc content. The nanomaterials of cobalt ferrite doped with zinc have Hc values in the range of 8.67–179.63 Oe, Mr values in the range of 1.33–16.90 emu/g, which are quite smaller than those of original CoFe2O4 material (Hc=497.89 Oe, Mr=36.29 emu/g); moreover, the nanomaterials prepared have Ms values in the range of 56.00 – 99.97 emu/g, which are similar to those of original CoFe2O4 material (Ms= 88.67 emu/g) and are quite higher than those of original ZnFe2O4 material (Ms ~ 1.2 emu/g).
