O 47: Focus Session: Atomic-Scale Studies of Spins on Surfaces with Scanning Tunneling Microscopy 1
Mittwoch, 7. September 2022, 15:00–18:00, S051
Magnetic single atoms and molecules are intensively studied as the smallest building blocks for potential applications in spintronic devices and quantum information processing. Detecting and controlling single spin states and their spin interactions require both high energy resolutions and atomic scale imaging capability. Scanning tunneling microscopes provide not only the spatial resolutions but also the bottom up approach to build magnetic structures atom by atom. Recently, unprecedented spin sensitivities have been reached by functionalizing the STM tips or by combining STM with electron spin resonance. The goal of this symposium is to highlight the recent developments in the rapidly evolving field of atomic scale sensing and quantum control of spins on surfaces. Researchers that use STM to investigate atomic or molecular spins on surfaces will present their most recent results. Sharing technical advances and addressing current issues will create synergies to foster future progress in this field and a deeper understanding of the underlying physics.
