(2) Other Magnetic Materials RE Giant Magnetostrictive Materials (GMM) Research of GMM in China started since 1980s but developed rapidly. The products can be produced in batches today. However, application of such materials in apparatus is laggard than developed countries. GMM materials are mainly applied in step motors, linear actuators, ultrasonic systems, sonar systems, valves, precise controls, active vibration damping etc. It is estimated that the near 10 years will be the fast developing period of global GMM market.
