| Abstract: | The measurement system of magnetomechanical coupling coefficient for giant magnetostrictive materials has been built by using a lock-in amplifier, according to the measurement theory. The magnetomechanical coupling coefficient has been measured in the system and it has been shown that the measurement valu-e of the magnetomechanical coupling coefficient is accurate and reliable. |
