Micro-structural characterization and magnetic study of Ni1.5Fe1.5O4 ferrite synthesized through coprecipitation route at different pHÂ values

Variation of lattice parameter with annealing temperature (a) and pH values (b) for samples prepared at specific pH and annealed at specific temperature, respectively, variation of crystalline size with annealing temperature (c) and pH values (d) for samples prepared at specific pH and annealed at specific temperature, respectively. Inset of (c) shows a typical example of the linear fit to calculate crystalline size of NFpH8_800 sample.
