摘要：

In Y/Fe/Y layered structures the Fe interlayer grows in an amorphous structure up to a critical thickness of d(Fe) = 2.3 nm. Above this thickness the Fe film transforms to a nanocrystalline structure. The magnetic properties of the amorphous Fe film (a-Fe) were determined by means of Fe-57 conversion electron Mossbauer spectroscopy and magnetization measurements. The average magnetic moment of a-Fe amounts to muBAR = (1.2 +/- 0.2)mu(B) and the ferromagnetic Curie temperature to T(c) = (80 +/- 3) K. There seems to be a broad distribution of the magnitude of the magnetic moments. No indication of spin glass properties was found.
