  • Publication number: 20200105997
    Abstract: Provided herein is an FeGa-base magnetostriction element that has specific characteristics with regards to magnetostriction along the longitudinal direction, and that shows a sufficiently high magnetostriction level along the longitudinal direction. The magnetostriction element is formed of a magnetostrictive material that is a monocrystalline alloy represented by Fe(100-?)Ga? (? represents the Ga content (at %), and satisfies 14???19) or Fe(100-?-?)Ga?X? (? and ? represent the Ga content (at %) and the X content (at %), respectively, X is at least one element selected from the group consisting of Sm, Eu, Gd, Tb, Dy, Cu, and C, and the formula satisfies 14???19, and 0.5???1).
