“…Many research groups are working on optimizing the magnetic and electrical properties of such ferrites by varying parameters such as temperature, pH, complexing agent, etc. Shelar et al (2010) reported the synthesis of nickel cadmium ferrites, Ni 1−x Cd x Fe 2 O 4 , using self propagating combustion method and observed that the increase in cadmium concentration expands the lattice parameter, in accordance with Vegard's law. The saturation magnetization increases as the Cd content is increased.…”

Synthesis of non-collinear (spin canted) ferrites having the formula, CoCd x Fe 2−x O 4 (x = 0•0, 0•2, 0•4, 0•6, 0•8 and 1•0), has been carried out using the sol-gel auto combustion method. The ferrite samples show an interesting magnetic transition from Neel to Yafet-Kittel configuration, as the Cd 2+ concentration is increased beyond x = 0•4. The FT-IR spectra confirm the formation of the metal oxide bond as they exhibit two frequency bands in the range of ∼595 cm −1 and ∼450 cm −1 , corresponding to the tetrahedral and the octahedral stretching vibrations of the metal oxide, respectively. The structural evolutions of the nanophase investigated using powder X-ray diffraction (XRD) technique show that the average crystallite size is ∼35 nm. The magnetic studies reveal that the saturation magnetization, M s , increases up to x = 0•4 and decreases when the value of x is >0•4. It is proposed that the incorporation of Cd 2+ ion takes place into the tetrahedral sites and up to x = 0•4, Neel's model is followed. But for x > 0•4, canting of spins occurs, as explained by Yafet-Kittel (Y-K) model. The d.c. resistivity decreases as a function of temperature, indicating semiconducting nature of the ferrites and the positive value of Seebeck coefficient establishes p-type conduction behaviour for all the ferrite samples.

“…Nickel cadmium (Ni-Cd) ferrite has many microwave applications for its high value of coercivity, remanence, and saturation magnetization [3]. Cd Ni 1− Fe 2 O 4 was investigated by Shelar et al [6] and the saturation magnetization showed an increase with the Cd-content. Magnesium ferrite is a soft magnetic material that is utilized in transformer cores and catalysts [7,8].…”

Magnesium substituted nickel cadmium ferrite nanoparticles MgxNi0.6−xCd0.4Fe2O4(fromx= 0 to 0.6 with step 0.1) have been synthesized by the chemical coprecipitation route. X-ray diffraction (XRD) and infrared spectroscopy (FTIR) revealed that the obtained powders have a single phase of cubic spinel structure. The crystallite sizes calculated from XRD data have been confirmed using transmission electron microscopy (TEM) showing that the powders are consisting of nanosized grains with an average size range 5–1.5 nm. Magnetic hysteresis loops were traced at 6.5 K as well as at room temperature using VSM. It was found that, due to the Mg2+-ions substitution, the values of saturation magnetizationMsfor the investigated samples were decreased, whereas the coercive fieldHcincreased. Both zero field cooling (ZFC) and field cooling (FC) curves are measured in the temperature range (6.5–350 K) and the values of blocking temperatureTBwere determined. No considerable variation in the values ofTBwas observed with increasing Mg-content, whereas the values of the effective anisotropy constantKeffwere increased.
