Shielding apparatus, shielding method and demagnetizing for measuring magnetic field
The present invention relates to a shield apparatus and a shield method for measuring a subtle magnetic field. More specifically, the present invention relates to a shield apparatus having a precise magnetic sensor therein, for shielding an external magnetic field in a subtle magnetic field measurement apparatus including a magnetic field generation apparatus for exciting a sample, the shield apparatus for measuring a subtle magnetic field, including: a shield wall provided with a high-conductivity metal layer of high conductivity being partitioned into a plurality of segments and having a high-frequency shield property and a closed high-permeability soft magnetic layer spaced apart from the high-conductivity metal layer by a predetermined distance, so as to seal a measurement space.
