Spin-Polarized Scanning Tunneling Microscopy: STM Magnetic Imaging of Nano Materials
Abstract: Spin-polarized scanning tunneling microscopy (SP-STM) shows surface electronic spin and quantum structures of nano materials, such as single atoms, single molecules, nano-clusters, with a resolution of atomic scale. With a combination of SP-STM spectroscopy mode we can directly observe the electronic spin band structures near the Fermi energy (±3 eV) of nano materials, and therefore this technique is one of the most powerful tools for development of new nano spintronics devices.
