Abstract :
A magnetoelectric hysteresis loop measurement system based on dynamic method was built under a demodulation concept with a lock-in amplifier as the high speed demodulator. A measuring speed as fast as 300 ms/point was achieved, and a complete and fluent magnetoelectric hysteresis loop could be obtained within minutes. Results show that the static magnetic phenomenon affects magnetoelectric effect significantly. This method is recommended to be the standard for magnetoelectric hysteresis loop measurement.
