Resumo
Several synthetic hematites have been analysed by X-ray diffraction and M~Sssbauer
spectroscopy. They have tabular shape and their Morin transition at 85 K show a dependence
on the ratio (R) of the sizes in c and a directions. The Morin transition has been observed
for samples with R = 0.43 _+ 0.05.
