摘要：
An FeAu ordered alloy has been fabricated artificially by depositing alternately monatomic layers of Fe and Au. Neither intermediate phase nor intermetallic compound is known for the Fe-Au system in the equilibrium state. Nevertheless, the x-ray diffraction for prepared FeAu films shows definite superlattice lines corresponding to the L1(0) ordered structure, and it is metastable at room temperature. The obtained FeAu 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.
