摘要：

The magnetic phases of fcc Fe(100) in Fe(100)/Cu1-xAux(100) multilayers with lattice parameters in the range a=3.606 to 3.704 have been studied using Mössbauer spectroscopy and SQUID magnetometry. The Fe layers have a two-phase structure consisting of a low-spin antiferromagnetic (AF) and a high-spin ferromagnetic (FM) phase. The average Fe moment and the relative population of FM Fe both increase with a, but the hyperfine magnetic field for the FM phase is not dependent on a, indicating that the increase in moment comes only from the FM phase population increase. © 1995 The American Physical Society.
