“…The data reported are an average of at least three readings. It can be seen that lattice parameter increases proportionally to the manganese content x, which may be a direct consequence of the larger ionic radius of Mn 2+ (0.91Å) as compared to Zn 2+ (0.82Å), as also discussed by different authors [1,11].…”

A series of CoAl x Cr x Fe 2-2x O 4 systems (x = 0.1 to 0.5 in steps of x = 0.1) spinel ferrites have been synthesized successfully using wet chemical co-precipitation technique. The samples were characterized by X-ray diffraction (XRD), infrared spectroscopy (IR) and magnetization measurements. The powder XRD patterns confirm the single phase spinel structure for the materials synthesized. X -ray diffraction measurements were performed to yield the lattice constant as function of the amount x corresponding to Al-Cr substitution. Lattice parameters, X-ray density, bulk density and particle size decrease whereas porosity increases with the increase in Al-Cr content, 'x'. Infrared studies show two absorption bands at about 400 cm -1 and 600 cm -1 for octahedral and tetrahedral sites, respectively. Saturation magnetization decreases with the increase in Al-Cr content x. AC magnetic susceptibility measurements were carried out as a function of temperature to measure the Curie temperature, which was found to decrease with Al-Cr content x. The decrease of Curie temperature has been explained by A-B interaction. Sp. z o.o. © Versita
