“…Among the various ferrites, cobalt ferrites have received recent attention as they possess excellent chemical stability, good mechanical hardness, remarkably high electrical resistivity, and large permeability at high frequency and cost effectiveness [3,4]. Due to these properties, cobalt ferrites have been extensively used in electronic devices [3,4], Magnetic Resonance Imaging (MRI), Target drug delivery, Hyperthermia for cancer treatment [5,6], high density storage devices, magnetic fluids [7,8], transformer cores, microwave devices, humidity and gas sensors, etc. Substitution of elements such as Chromium into Cobalt ferrites has been proposed, in order to tailor the magnetic and magneto mechanical properties of these materials [9].…”

Co-Cr nano-ferrites, having the chemical formula CoCr x Fe 2-x O 4 (where x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0), were synthesized by the Citrate-gel auto combustion method. Synthesized powders were sintered at 500˚C for 4 hours in an air and were characterized by XRD, SEM and EDS. XRD analysis showed cubic spinel structure of the ferrites and the crystallite sizes (D) were found in the range of 6-12 nm. The values of lattice parameter (a) decreased and X-ray density (d x) increased with the increase of Cr content. Scanning Electron Microscopic (SEM) studies revealed nano crystalline nature of the samples. An elemental composition of the samples was studied by Energy Dispersive Spectroscopy (EDS). The observed results can be explained on the basis of composition and crystal size.

“…Ferrite nanoparticles have been widely studied given their range of potential applications. They can be used for cancer treatment [1], in ferrofluids [2], for drug delivery [3], and as magneto-optical recording media [4,5], among others. Cobalt ferrite nanoparticles are a material with attractive characteristics for use in magneto-optical recording media.…”

Characterization and optimization of material properties during synthesis and processing are frequent problems in materials science and engineering. In the present paper, the use of design of experiments (DOE) to characterize and improve coercivity in cobalt ferrite nanoparticles is described. The sequence of experiments was planned to capitalize on previous experimental runs available. Emphasis is placed on the rationale for choosing the additional runs. The results reveal that the choice of an adequate initial experimental design can save effort and resources in arriving at useful conclusions upon which subsequent experimental runs can be planned, capitalizing on the initial experimental structure. A region with attractive solutions in terms of coercivity, including a local maximum, was identified through the experimental sequences described in this case study.
