Bridging the Interface : Probing and Designing Molecular Spin Systems
Germar Hoffmann, Institute of Physics, Academia Sinica, Taipei, Taiwan
The last two decades saw a vital development into the field of
nanomagnetism. The research in physics and device fabrication
significantly progressed in terms of experimental techniques,
theoretical understanding, and design of magnetic nanoparticles.
However, the question remains on how to reliably fabricate new kind of
devices for future applications. Parallel to the development in
technically oriented disciplines, molecular magnetism emerged from
chemistry. Molecular magnetism offers new routes for the development
of multi-functional materials for the precise control of spin states.
Thereby, the production costs are low and reproducibility down to the
last atom is granted. However, the experimental access is so far
limited to precisely understand the physical mechanisms within such
complex multi-functional systems.
In my talk, I will present latest results from my research crossing
the border between classical chemistry and fundamental physics.
Resolved by scanning tunneling microscopy, the behavior of static and
dynamic molecular spin systems of synthesized and artificial molecules
is addressed in spin-polarized tunneling and electron spectroscopy and
implications for device fabrication and novel devices will be
discussed. The talk will be concluded by an outlook onto future /
planned experiments,
I intend to realize at the ESPCI.
