The system is simple in structure, can carry out various types of magnetoelectric performance tests, effectively reduces the test cost, can achieve the precise control of a test variable, andimproves the test precision.

Description

technical field [0001] The invention relates to the technical field of magnetoelectric testing, in particular to a high-precision multifunctional temperature-variable magnetoelectric testing system. Background technique [0002] The magnetoelectric effect includes the electric effect of the magnetic field and the magnetoelectric effect in the narrow sense. The electric effect of a magnetic field refers to the electric effect caused by a magnetic field on an object passing a current, such as the magnetoresistance effect and the Hall effect; the magnetoelectric effect in a narrow sense refers to the magnetization effect of an object produced by an electric field or the electric polarization produced by a magnetic field Effects such as electromagnetoelectric or magnetomagnetic effects. After an external magnetic field is applied, the resistivity of the material changes due to the action of the magnetic field. For non-ferromagnetic substances, an external magnetic field usuall...
