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.en-USrestritoArtigo publicado em periodicohttps://link.springer.com/article/10.1007/BF02398191https://doi.org/10.1007/BF02398191
