Structure and magnetism of the RTiFe/sub 11/ compounds (R=Gd, Tb, Dy, Ho, and Er)
- MEMS Dept., Carnegie-Mellon Univ., Pittsburgh, PA (US)
The authors discuss the preparation and investigation of ternary alloys of the composition RTiFe/sub 11/ (R = Gd, Tb, Dy, Ho and Er). These samples were found to be nearly single phase materials, having small amount of extraneous phases appearing primarily along the grain boundaries. The Curie temperatures were observed to be in the range of 502 to 603 K and vary with the R component according to the square root of the de Gennes function, reflecting the R-Fe exchange interaction. All of the compounds studied, except TbTiFe/sub 11/ possess uniaxial anisotropy at room temperature. The results obtained indicate that, in these systems, the R and Fe sublattices couple antiparallel, as is normally the case in heavy rare earth - transition metal compounds.
