Abstract
An FeAu ordered alloy has been fabricated artificially by depositing a lternately monatomic layers of Fe and Au. Neither intermediate phase n or intermetallic compound is known for the Fe-Au system in the equilib rium state. Nevertheless, the x-ray diffraction for prepared FeAu film s shows definite superlattice lines corresponding to the L1(0) ordered structure, and it is metastable at room temperature. The obtained FeA u ordered alloy is ferromagnetic, and it has the Fe moment of 2.5 +/- 0.3 mu(B), a considerably high Curie temperature over room temperature , and a large uniaxial magnetic anisotropy perpendicular to Fe and Au atomic planes.
