Abstract

Several synthetic hematites have been analysed by X-ray diffraction and Mössbauer spectroscopy. They have tabular shape and their Morin transition at 85 K show a dependence on the ratio (R) of the sizes inc anda directions. The Morin transition has been observed for samples withR=0.43±0.05.
