Engineering Spin Interaction Channels of FePc on Au(111)

We demonstrate the reversible control of interactions between a local molecular spin, hosted within an iron phthalocyanine (FePc) molecule, and the conduction electrons of a supporting Au(111) surface. Using the tip of a scanning tunneling microscope, we d ...

Highlights of the Science and Life of Peter Varga (1946-2018)

Wolf-Dieter Schneider

Peter Varga has passed on October 27, 2018. His pioneering discoveries of chemical resolution at the atomic scale on surface alloys, atomic resolution of ultrathin alkali halides, nucleation of bcc iron in ultrathin films, and the microscopic structure of ...

Sensing the Spin of an Individual Ce Adatom

Wolf-Dieter Schneider, Markus Ternes

The magnetic moment of rare earth elements originates from electrons in the partially filled 4f orbitals. Accessing this moment electrically by scanning tunneling spectroscopy is hampered by shielding of outerlying orbitals. Here, we show that we can detec ...

Phonon-Mediated Electron Transport through CaO Thin Films

Wolf-Dieter Schneider, Giulia Elisabetta Pacchioni

Scanning tunneling microscopy has developed into a powerful tool for the characterization of conductive surfaces, for which the overlap of tip and sample wave functions determines the image contrast. On insulating layers, as the CaO thin film grown on Mo(0 ...
