Abstract Recent advancements in nanotechnology have rapidly promoted research on developing novel nano‐sized MNPs with satisfactory biocompatibility for biomedical applications. This study synthesized Ni x Fe 3−x O 4 (with = from 0 to 1.0) coated CTAB hydrothermal and coprecipitation methods the medical imaging systems as a tracer agent. The structural properties of CTAB‐coated MNPs, including crystalline lattice, composition, morphological pattern, are characterized an X‐ray, SEM, EDS, results confirmed formation highly magnetite spherical shaped NPs presence CTAB. cell constant average crystallite size determined 8.33–8.40 nm 10.5–18.6 nm, respectively. FT‐IR is recorded detect NH 2 CH bands, confirming successful coating. saturation magnetization particles measured between 50–80 emu g −1 PPMS. dynamic response agents alternating magnetic fields also MPS at 9.9 kHz. Effective relaxation time, FWHM nanoparticle's signals, frequency spectrum evaluated. MTT analysis indicates low cytotoxicity high NiFe NPs.
