Exploiting YSR States for Driving Spin Transitions in a Magnetic Field — •Maneesha Ismail1, Juan Carlos Cuevas2, and Christian R. Ast1 — 1Max-Planck-Institute for Solid State Research, Stuttgart, Germany — 2Universidad Autónoma de Madrid, Madrid, Spain
In recent years, advances in the field of atomic scale electron spin resonance (ESR-STM) have made it possible to manipulate single spins and observe their interaction [1,2]. In this work, we exploit the tip confinement of superconductivity in a magnetic field to explore a new candidate system, namely Yu-Shiba-Rusinov states. We present how the Zeeman-split states behave under microwave irradiation. Our theory, which is based on a Green’s function approach, corroborates the idea that the presence of the YSR state can be used to detect a change in the spin population. A new sample system could open the path to observing new phenomena in the field of spintronics and quantum computing.
