It is demonstrated that the sensitivity of a standard Hall magnetometer can be increased from about 2.5·10−7 T to about 3.6·10−9 T through the generation of a sharp jump of magnetic response at the first thermodynamic critical field Hic1 of sub- and nanocrystallites in the sensitive element based on an YBa2Cu3O7-x epitaxial film deposited parallel to the surface of a Hall transducer (HT) by a decaying oscillating local magnetic field (DOLMF). The dynamic range of the magnetometer is extended to the region of weak fields from (2.5·10−7–1.2·10−1) T to (3.6·10−9–10−2) T, while maintaining an accuracy of 0.01% and 0.1% linearity of induction measurement. To increase the linearity and noise immunity, the working region of the Hall magnetometer is shifted to higher fields, which coincide with the Hic1 of twins in the superconductor. A stepwise variation in the amplitude of the DOLMF provides high spatial resolution of the HT throughout the working range of the magnetometer irrespective of the high values of sensitivity, accuracy, and linearity.
