Abstract
Nanocrystalline alloys, produced by partial devitrification of melt-spun amorphous precursor, exhibit a two-phase structure with nanocrystalline bcc grains dispersed in the residual amorphous matrix. This was first established for FINEMET [1] followed by NANOPERM [2,3] and HITPERM [4]. The soft magnetic properties are due to the reduction of effective magnetic anisotropy randomly averaged by exchange interaction and is related to the refinement of the grain size [5].
