Effect of Zn2+–Cr3+ substitution on structural, morphological, magnetic and electrical properties of NiFe2O4 ferrite nanoparticles

The influence of aluminum’s crystalline structure on the elastic, dielectric, and electrical properties of Ni ferrite

“…from 3.594 to 3.519 (Å) and from 2.934 to 2.873(Å) for the A-sites and B-sites, respectively [20]. The average crystallite size was estimated from the reflected peaks of the x-ray diffraction pattern using the Debye-Scherrer formula: it ranges from 22.4-24.7 nm for all samples [21]. Porosity P was calculated using the relation P 1 where M is the molecular weight, N is the Avogadro number, and a is the experimental lattice constant [22].…”

Synthesis of Ultra‐fine Co1‐(x+y)NixZnyFe2O4 Ferrite Nanoparticles: Customizing Magnetic Properties

“…Due to their peculiar magnetic properties and small dimensions, magnetic nanoparticles (MNPs) have a wide variety of properties and hence applications in different areas of science and technology, including electromagnetic sensors and devices [1,2] , MRI imaging [3] , design and fabrication of biomedical devices [3] , hyperthermia increasing temperature of cancerous tissue [4,5] , drug delivery and other biomedical applications [6][7][8][9] , electrochemical sensors [10] , supercapacitor applications [10] , water purification [11] and so on. Being more precise, in biomedical applications, by approaching the nanosize scale, one can get close to biological entities of interest.…”

“…In this paper, in the presence of citric acid, Cobalt, Nickel, and Zinc ion concentrations have been tuned to reduce the toxicity of MNPs and find a good pattern. There are different synthesis methods for ferrite MNPs such as auto-combustion synthesis, co-precipitation method [33,[38][39][40][41] , mechanical alloying [42] , sol-gel [2,43] , and so on. Each method has advantages over the other methods.…”
