Atomic migration in Co0.9Zn0.1Fe2O4

Abstract Co 0.9 Zn 0.1 Fe 2 O 4 ferrite has been studied with Mossbauer spectroscopy and X-ray diffraction. Mossbauer spectra of Co 0.9 Zn 0.1 Fe 2 O 4 measured at various absorber temperatures of 20–830 K. Its Neel temperature T N is found to be 790 K. Atomic migration of Co 0.9 Zn 0.1 Fe 2 O 4 starts near 295 K and increases rapidly with increasing temperature to such a degree that 78% of the ferric ions at the A sites have moved over to the B sites by 700 K.
