5.The rare earth-iron intermetallic compounds of SmTiFex with x ranges from 8 to 11, was synthesized by are-melting technic. We found that they crystallize in the ThMn12-type tetragonal structure, 14/mmm. We report here the crystallographic and magnetic properties of Sm(Ti, Fe)12 and Gd (Ti, Fe)12. Unusual uniaxial magnetocrystalline anisotropy was observed in Sm(Ti, Fe)12 compounds.
