摘要: Abstract The effect of transformations induced by annealing on the structure and magnetic properties α-Fe2O3 antiferromagnetic nanoparticles synthesized chemical route has been investigated transmission electron microscopy, magnetization measurements Mossbauer spectroscopy. Annealing these samples re-crystallize without changing its mean size modifying crystalline anisotropy energy leading to a change in reversible–irreversible regime Morin transition behaviour.
