.The as-prepared Mn 0.5 Cd x Sr 0.5- x Fe 2 O 4 nanocrystals, ( x = 0, 0.1, 0.2, 0.3, 0.4, 0.5), were synthesized by the one-beaker and smart co-precipitation strategy, thereafter nanocrystals were well-characterized by X-ray diffraction (XRD), FT-IR spectra, higher resolution transmission electrons microscopy (HTEM) and vibrating Nano-samples magnetometry (VSM) strategies. XRD investigation proved the evolution of the single-phase spinel structure for all nano-spinels. The crystallite size R values ranged from 16.05 – to – 32.1 nm, with declining behavior with Cd 2+ cationic ratio x . FT-IR absorption spectrum displayed 6-absorption bands that were related to their principle sites and main bonds. The elicited parameters were influenced by the Cd 2+ cations replacement instead of Sr 2+ cations. Magnetic merits proved the soft-magnetic features for all these nanocrystals, whereas, all the magnetic parameters were influenced by the replacement process with Cd 2+ cations. HTEM images exhibited aggregations in these ultrafine nanoparticles. The nanoparticles sizes Z ranged from 20 – to – 35 nm a little greater compared with crystallite sizes R.
