Tb-Dy-Fe single crystal and magnetostrictive actuator using these materials

摘要

Magnetostrictive actuators normally use twin-crystal magnetostrictive materials as dirving unit. Because the crystal and twin-crystal hinder the movement of the domain wall, its displacement output of low Magnetic strength is rather small. Using Tb-Dy-Fe single technique can effectively solve the problems Brought by pollution and twin crystals, and produce high-quality Tb-Dy-Fe single crystal materials. The paper Will introduce the technique of using these materials to produce magnetostrictive actuators that posses high sensitivi- Ty and resolution and use pulse feeding.
