A magnetometer measurement is an experimental procedure in which a magnetometer is used to quantitatively determine the magnitude and/or vector components of a magnetic field or magnetic moment under defined conditions. In methodological terms, it encompasses instrument calibration, control of environmental magnetic noise, selection of measurement geometry, and acquisition protocols such as scanning, time-resolved, or field-swept modes. Depending on the magnetometer type (e.g., SQUID, vibrating sample, Hall-effect, fluxgate), the measurement constrains sensitivity, spatial resolution, dynamic range, and bandwidth, and is used to characterize material magnetization, field gradients, or local magnetic environments in fundamental research and applied sensing.
A research team has, for the first time, realized the quantum amplification of an extremely weak magnetic field by using dark spin, with the magnetic field magnification exceeding a factor of 5,000 and the single magnetic ...
