ABSTRACT:
A SmFe-based magnetostrictive material having an excellent magnetostrictive performance and an excellent mechanical strength provided by achieving a division of crystal grains. The SmFe-based magnetostrictive material includes boron (B) as an additive component, which contributes to the fine division of crystal grains. The content of boron (B) is set in a range of B.ltoreq.0.01% by weight.
