The effect of α-Fe crystallites on the magnetic structures of Fe100-xZrx glasses

Neutron scattering experiments with polarization analysis have established that Fe100-xZrx glasses have non-collinear ferromagnetic structures. The magnitudes of the non-collinear components are enhanced by small fractions of α-Fe precipitated in these glasses. Moessbauer spectroscopy has therefore been used to measure the fractions of α-Fe in two samples each of Fe90Zr10 and Fe92Zr8 metallic glasses, which are confirmed to contain up to 6 atomic % α-Fe. The measured fractions and their influence on the magnetic structures are discussed in the context of the existing literature on nanocrystalline FeZr.
