Tb-Dy-Fe Single Crystal and Magnetostrictive Actuator Using These Materials
摘要
Magnetostrictive actuators normally use twin-crystal magnetostrietive materials as driving unit. Because the crystal and twin- crystal plane hinder the movement of the domain wall, its displacement output of low magnetic strength is rather small. Using Tb-Dy-Fe single crystal 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 possess high sensitivity and resolution and use pulse feeding.
