An Experimental Research of Electromagnetic Parameters on Rare Earth Supermagnetostriction Materials

Applying self-made experimental device to test rare earth supermagnetostriction parameters through adopting an unique chemical technique to have produced a ternary rare earth alloy of Tb-DyFe, the supermagnetostriction factors of the magnetostriction bar known as rare earth alloy mentioned above, thus an electromechanical couplying factors and electromagnetic parameters are both put into an experiment and test.Furthermore, the paper discusses how the magnetoelectric couplying affects the magnetostriction factors and the electromechanical cauplying factors. This resulted in rendering important grounds for designing supermagnetostriction material to be used in electric devices or elements.
