Title: Exchange coupling in crystalline/amorphous Nd-Fe-B nanoassemblies

Abstract

The demagnetization behavior of nanoassembled crystalline/amorphous microstructures was investigated. The microstructures consisted of isolated Nd{sub 2}Fe{sub 14}B crystallites surrounded by regions of remaining amorphous phase. The hard magnetic crystallites interacted with the surrounding amorphous phase over a length scale of approximately 1.5-2 nm. As the extent of the amorphous phase decreased to less than this, interactions between hard magnetic grains were observed. (c) 2000 American Institute of Physics.
