    Influence of viscosity on dynamic magnetization of thermally blocked iron oxide nanoparticles characterized by a sensitive AC magnetometer by Mohd Mawardi, Saari, Nazatul Shareena, Suhaimi, Mohd Herwan, Sulaiman, Nurul Akmal, Che Lah, Sakai, Kenji, Kiwa, Toshihiko, Tsukada, Keiji

    Published 2019
    “…The core size of the nanoparticles was determined from the magnetization curve measured by a specially developed high-Tc SQUID magnetometer and calculated to be 11.7 nm. Using an AC magnetometer developed based on induction coils, the dynamic magnetization of the multi-core iron oxide nanoparticle solution was measured from 3 Hz to 10.48 kHz. …”

    Attitude anti-interference federal filtering algorithm for MEMS-SINS/GPS/magnetometer/SV integrated navigation system by Hongmei Zhang, Huaqing Zhang, Guangyan Xu, Hao Liu, Xin Liu

    Published 2020-01-01
    “…In order to eliminate the effect of magnetic field observations on the attitude information of pitch and roll angles, a method of correction update for a yaw angle component in quaternions using the magnetometer is designed, and an Euler angle information fusion method is developed by constructing a pseudo-covariance matrix of Euler angels in fusion update of the filter. …”

    Automated Machine Learning Strategies for Multi-Parameter Optimisation of a Caesium-Based Portable Zero-Field Magnetometer by Rach Dawson, Carolyn O’Dwyer, Edward Irwin, Marcin S. Mrozowski, Dominic Hunter, Stuart Ingleby, Erling Riis, Paul F. Griffin

    Published 2023-04-01
    “…Here we present a number of automated machine learning strategies utilised for optimisation of a single-beam caesium (Cs) spin exchange relaxation free (SERF) optically pumped magnetometer (OPM). The sensitivity of the OPM (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mrow><mi mathvariant="normal">T</mi><mo>/</mo></mrow><msqrt><mrow><mi>Hz</mi></mrow></msqrt></mrow></semantics></math></inline-formula>), is optimised through direct measurement of the noise floor, and indirectly through measurement of the on-resonance demodulated gradient (mV/nT) of the zero-field resonance. …”
