Spintronics research. Coloured scanning tunnelling micrograph (STM) showing ferromagnetic interactions between manganese atoms in a gallium arsenide semiconductor (blue). The spins of the atoms interact via a cloud of electrons (red and yellow). Gallium atoms in the semiconductor have been substituted by manganese atoms using the scanning tunnelling microscope,which allows precise substitution one atom at a time. This creates a magnetic semiconductor that would be able to store data as well as process it. This research is being carried out by Prof. Yazdani at Princeton Nanoscale Microscopy Laboratory (PNML),Princeton University,USA | |
