X-ray diffraction investigation of cation distribution in CdχCu1-χFe2O4 ferrite system

Effect of Fe3+ in Li-Mn Aluminates synthesized by co-precipitation method for the application of opto-magnetic and Magnetic refrigeration applications

“…The shift of peaks is in accordance with Bragg's law and substitution of dopant species [19,20]. The intensities of (220) and (440) planes are more sensitive to cations in tetrahedral and octahedral sites respectively [21,22]. From TABLE 1 it is clear that intensity of (440) decrease with increasing Fe 3+ and this expressing decreasing Al 3+ ions in the octahedral sites.…”

Effect of Mn2+ ions on Structural and Magnetic properties of Co-precipitated Ni-Cr nano ferrite for Potential applications as MRI Contrast agent

“…Intensity and peak width of XRD pattern related to particle size and crystallinity of the samples. The intensities of (220) and (440) planes are more sensitive to cations in tetrahedral and octahedral sites respectively [18,19]. From TABLE 1 it is clear that intensity of (440) and (220)varies nonlinearly with increase in Mn 2+ ion, this is due to presence of Fe 2+ ion in octahedral site formed due to reduction of Fe 3+ ion to Fe 2+ for higher Manganese concentration causes migration of ions and also decrease in Nickel at octahedral site [20].…”

Finite size effect and influence of temperature on electrical properties of nanocrystalline Ni–Cd ferrites

“…Diamagnetic ions substitution in ferrites has received a lot of attention over the past years [3][4][5][6]. The preference of non-magnetic ions in spinel ferrites has been found to alter their electrical and magnetic properties and studies have revealed useful information on the nature of the exchange interaction, direction of magnetization, cation distribution, spin canting, etc.…”
