Thermodynamically it is predicted that the magneto-electric effect occurs in materials where magnetic-electric or magneticelectric-elastic phases coexist. The magneto-electric coupling facilitates the modification of electric polarization when an external magnetic field is applied, and the modification of net magnetization due to the application of an external electric field. The effect is mathematically described by the magnetoelectric coupling coefficient. The magneto-electric coupling coefficient can be electrically induced describing the change in the magnetic induction of the sample due to the application of an electric field. The magneto-electric coupling measurement system is designed by our company are most advanced in its specifications and can undertake various tests needed by researchers.
