چکیده
|
Zinc substituted magnesium ferrite mg1-xznxfe2o4 (x = 0.5,0.7) powders have been prepared by a sol-gel autocombustion method. xrd patterns show that the specimens with x = 0. 5 and 0.7 exhibit single-phase spinel structure,and more content of zn in specimens is favorable for the synthesis of pure mg-zn ferrites. room temperature mössbauer spectra of mg1-xznxfe2o4 annealed at 800°c display transition from ferrimagnetic behavior to super paramagnetic behavior with increase in zinc concentration. the mössbauer spectras of mg0.5zn0.5fe2o4 annealed at different temperatures display the magnetic phase change of the ferrite particles. © 2014 jinpei lin et al.
