When the arrays are laid out along different spatial directions they can perform tensor gradiometry allowing the measurement of field components and their spatial derivatives as a function of orientation. Detection is based on using spin-polarized currents to counteract vortex displacements or to excite vortex oscillation modes triggered by magnetic-field application. Sensor linearization, field detection range and conditions to obtain large sensitivity electronic compatibility and scalability are discussed. %G English %L insu-03684937 %U https://insu.hal.science/insu-03684937 %~ INSU %~ UNIV-BREST %~ CNRS %~ LGO %~ GEO-OCEAN
