High-sensitivity magnetic field measurement method of Cr2Te3 asymmetric structure

The invention relates to the technical field of magnetic field detection, discloses a high-sensitivity magnetic field measurement method of a Cr2Te3 asymmetric structure, and provides a Cr2Te3 asymmetric array structure based on Fano magnetic field power frequency resonance by utilizing the characteristics of narrow linewidth and high spectral contrast of Fano resonance which are sensitive to the change of ambient environment input waves. The change condition of a magnetic field is induced by monitoring the change of Fano resonance in a Cr2Te3 asymmetric structure response spectrum, and the Fano resonance in the Cr2Te3 asymmetric array structure response spectrum is changed by utilizing the ferromagnetic characteristic that Cr-Te compound can generate magnetic resonance along with a power frequency magnetic field to be measured on the premise of constant magnetic field balance orbit plane precession. The Fano resonance has the grating characteristics of wide display narrow line, high spectral contrast and str
