Magnetoelectric Coupling Response Analasis of Piezomagneto-Piezoelectric Semiconductor Composite Simply Supported Beam under Constant Magnetic Field

We study the bending behavior of the composite fiber composed of piezomagnetic material and piezoelectric semiconductor material in the magnetic field. The top and bottom piezomagnetic layer are in opposite reverse polarization. The bending of the piezomagnetic material in the magnetic field causes the bending of the composite structure. The analytical expressions of the displacement, electric potential and carriers of the composite fiber were obtained. The results show that the magnetic field results in the redistribution of carriers in the composite fiber, and the magnetic field and the initial carrier concentration can regulate the electrical quantity of the composite fiber. Provides theoretical guidance for the design of piezoelectric electronics devices based on piezoelectric semiconductor-piezomagnetic materials.
