High resolution neutron powder diffraction has been used to determine the crystal structures of YFe11Ti and YFe10Ti intermetallic compounds.

Abstract
High resolution neutron powder diffraction has been used to determine the crystal structures of YFe11Ti and YFe10Ti intermetallic compounds. Both compounds crystallize in the ThMn12 tetragonal structure (space group I4/mmm). The 8j and 8f sites are virtually fully occupied by ⊢e whilst the 8i site is partially occupied by Fe and Ti atoms. The temperature dependence of the magnetic anisotropy from 293 to 78 K has been measured by the singular point detection technique. The magnetic anisotropy is found to increase with decreasing temperature. The value of the anisotropy field is 37KOe and 21KOe at 78K and 293K respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
