"observations of individual atomic layers' magnetic fields within crystalline solid using defocus correction algorithms... automates device's control/ tuning speeding up imaging to 10K images over 8.5 hours, minimizes noise obtaining much clearer images containing distinct electric/ magnetic field data... correct for defocusing due to minor focus shifts by analyzing reconstructed electron waves, so free of residual aberrations... atoms' positions/ phases easily discernible with magnetic field"
