Abstract
AbstractOne of the most significant effects of reducing the structural correlation length of ferromagnetic materials to a nanometer scale is magnetic softening. This softening is brought about by the reduced effect of the intrinsic magnetocrystalline anisotropy due to the mutual transmission of the anisotropy energy among a great number of nanocrystallites. This softening effect provides us with an alternative approach to the development of novel soft magnetic materials. Nanocrystalline soft magnetic alloys prepared by annealing melt-spun amorphous precursors, with which this chapter is concerned, are one of the latest successful outcomes of such a new approach to the development of novel soft magnetic materials. In this chapter we will discuss the history, origin of the softness, processing and properties of the nanocrystalline soft magnetic alloys with particular attention paid to: ①nanostructure-magnetic properties relationships and ② the principles underlying material design.KeywordsAnisotropy EnergyMagnetocrystalline AnisotropyCore LossSoft Magnetic PropertyNanocrystalline AlloyThese keywords were added by machine and not by the authors.
