Abstract :
The correlation between the direct magnetoelectric (ME) effect and the magnetization of planar ferromagnetic (FM)-piezoelectric composite structures has been demonstrated. It is experimentally proved that for unsaturated layers of FM galfenol, permendur, amorphous alloy, and nickel, the magnetostriction is the quadratic function of the magnetization. Using a langatate-nickel structure with magnetic hysteresis as an example, it has been shown that the dc magnetic field dependence of ME interaction efficiency can be calculated and predicted using magnetization curves for the FM layer.
