โœฆ Synopsis

The local structure around Fe in Fe/Cu and Fe/Ag granular materials has been studied by means of extended X-ray absorption fine structure (EXAFS). In the Cu matrix, the structure of the Fe cluster is FCC for Fe concentrations less than 22 at%, while it is BCC for more than 35 at% Fe. In the Ag matrix, on the other hand, the structure of the Fe cluster is BCC even for Fe concentrations down to 12 at%.

In-situ Brillouin light scattering has been used to study the magnetic anisotropy of thin Fe(110) films grown by e-beam evaporation on a Cu(110) single crystal. Structural analysis revealed that, as the Fe thickness exceeds about 4-6 A, a fcc-bcc phase transition occurs. Measurement of the Damon-Esh
