Mapping method of magnetoelectric loop wire of magnetoelectric material

Abstract

The invention relates to a m magnetoelectric material, especially to a mapping method of a magnetoelectric loop wire of a magnetoelectric material. Mapping is carried out on a series of alternating magnetoelectric signals that include amplitudes and phases as well as are measured by under a direct current magnetic field and are stored in a text file in a way of a polar coordinate and a rectangular coordinate, and a polar coordinate plate can be called as a signal complex plane; an interference vector generated by Faraday induction of a lead wire is determined as well as interference vector deduction is carried out on the magnetoelectric signals measured at all the direct current magnetic fields, so that rectified magnetoelectric signals are obtained; and mapping is again carried out on the magnetoelectric signals that have been processed by the interference vector deduction in the complex plane as well as any point is taken on a vertical symmetric axis of a magnetoelectric 8-shaped loop wire to arrange the size of an overturned phase; according to the overturned phase, a magnetoelectric signal that is arranged above the overturned phase is a positive one and a magnetoelectric signal that is arranged below the overturned phase is a negative one; and the magnetoelectric signals that have been arranged with positive and negative properties are used to form a vertical coordinate and the direct current magnetic fields are used to form a horizontal coordinate, so that a magnetoelectric loop wire is obtained by mapping.

Description

Technical field [0001] The invention relates to a magnetoelectric material, in particular to a drawing method of the magnetoelectric loop of the magnetoelectric material. Background technique [0002] Magnetoelectric effect is the physical effect of applying a magnetic field to some multiferroic compounds and ferroelectric / ferromagnetic composite materials to generate an electric field. Materials with magnetoelectric effect are collectively called magnetoelectric materials. At present, the commonly used method to measure the magnetoelectric effect is the dynamic method. The specific process is to use a DC magnetic field to bias the magnetoelectric material, and then superimpose a small alternating perturbation magnetic field on the DC magnetic field. A voltage or charge signal generated on an electrical material. Since the magnetostrictive behavior of ferromagnets has nothing to do with the direction of the DC magnetic field, the magnitude of the magnetoelectric effect is symmet...
