Unlike standard AFM, the NW-based technique enables measurements of both the size and direction of forces. He later showed that magnet-tipped NWs can be used for imaging extremely weak magnetic field patterns on the nanometer-scale, as required for mapping mesoscopic transport and spin textures or in nanometer-scale magnetic resonance.
