Atomically assembled quantum spin lattices
Sander Otte, Kavli Institute of Nanoscience Delft, The Netherlands
The physical behavior of lattices consisting of coupled quantum spins is often
hard to predict, even when only few spins are involved. Yet, insight into such
basic lattices can be key towards understanding the fascinating properties of
complex magnetic materials on the macroscopic scale.
In our lab we study small one- and two-dimensional lattices of magnetic
atoms by building them from scratch, literally atom-by-atom, using low temperature
scanning tunneling microscopy. Once built, the atomic structures
can be probed locally using a combination of inelastic electron tunneling
spectroscopy (IETS) and spin-polarized STM.
