Intrinsic magnetic properties of SmTiFe10

Abstract

The rare‐earth–iron intermetallic compounds SmTiFe_x, with x ranging between 8 and 10, have been synthesized by an arc‐melting technique. We found that they crystallize in the ThMn₁₂‐type tetragonal structure, I4/mmm. Unusual uniaxial magnetocrystalline anisotropies have been observed. The c axis is the easy magnetization direction. Curie temperature is 610 K. After the discovery of the R₂Fe₁₄B compounds, we have other ternary rare‐earth–iron intermetallic compounds with strong uniaxial anisotropy.
