“…Figure 1(b) displays Rietveld fitted X-ray diffractograms for the same samples. One of the most important Rietveld error indices or discrepancy values is that of "Chi-squared" or c 2 [5]. It is found that c 2 for different samples lie in the range 1.2-1.4.…”

The X-ray Debye temperatures, q M , of spinel ferrite composition Ni 0.5 Zn 0.5 Fe 2 O 4, mechanically milled upto 9 hrs, were determined from integrated intensities of selected Bragg reflections. The q M was found to increase with milling time. The results are explained in the light of milling induced grain orientation and surface effect. The values of q M were found to be lower as compared to the Debye temperatures obtained from infrared spectral data analysis. The difference can be explained on the basis of increase in an excess free volume in the form of vacancies and vacancy clusters associated with grain boundaries.

“…Increments of these contacts, reduction of particle size and storage of strain energy in particles are the most important reasons for increasing the kinetics of reactions and lowering the reaction temperature [9]. By controlling the milling power (MP) and milling time (MT), allied to the sintering temperature, high-energy ball milling processing is also a promising technique for producing a wide range of nanostructures and magnetic nanocomposites [10][11][12][13][14].…”
