Abstract

Summary form only given. Ultrasoft nanocrystalline alloys prepared by controlled heat treatment of amorphous precursors are interesting for their magnetic properties specially combined with high permeability. The ultrafine grain structure of the order of few or several nanometres embedded in the residual amorphous matrix is responsible for the magnetism of the alloy. Diverse techniques are used for structural and magnetic investigations in order to understand such two-phase magnetic systems, using Ni/sub 64/Fe/sub 16/Zr/sub 7/B/sub 12/Au/sub 1/.
