The cation distribution of spinel ferrites can be determined from Rietveld refinement data. The following steps should be followed: 1. Obtain the unit cell parameters, such as the lattice parameters, from the Rietveld refinement data. 2. Calculate the cation distribution using the lattice parameters and the cation size. 3. The cation distribution can then be calculated using the formula: Cation distribution = (cation size/lattice parameter) x 100.
