Annealing effects on the crystal growth and the magnetic properties of Mn0.8Zn0.1Ni0.1Fe2O4 ferrite powder grown by using the sol-gel method

Nickel Substitution Effects on Nano-sized Co, Mn and MnZn Ferrites Synthesized by Sol-gel Method

“…The Mössbauer absorption spectra can be explained to be a result of the variation in the magnetic phase resulting due to the particle sizes. As shown for Mn 1-2x Zn x Ni x Fe 2 O 4 ferrite powders [10,15], the Mössbauer spectra for the x = 0.0 sample annealed at 523 K and the x = 0.1 sample annealed at 473 K are attributed to paramagnetic behavior. This originates from the small particle size, and the superparamagnetic properties were confirmed by the low-temperature Mössbauer spectra.…”
