The origin of high thermal stability of magnetic softness in Fe/Fe-Hf-C nanocrystalline multilayers with high IS(=2.0T) was investigated in relation to their microstructure. The layered structure and nanocrystalline state was found to be stable up to about 1000 K. It was considered that the stable HfC precipitates in the Fe-Hf-C layer was responsible for such high stability.
