Nanoscale imaging of spin textures with single spins in diamond — •Patrick Maletinsky — Department of Physics, Basel University, Switzerland
Quantum two-level systems offer attractive opportunities for sensing and imaging at the nanoscale. Since its inception, this idea  has advanced from proof of concept  to a mature quantum technology , which finds applications in condensed matter physics, materials science and engineering. In this talk, I will discuss our approach to realizing such quantum sensors  and highlight some particularly rewarding applications in the imaging of nanoscale spin textures.
Specifically, I will discuss how we employ single electronic spins in diamond for nanoscale probing of antiferromagnetic systems [5,6] and high-resolution imaging of atomically thin van der Waals magnets . For both, the combination of sensitivity, spatial resolution and quantitative imaging enables unprecedented insights into nanoscale domains and domain-walls down to the atomic monolayer limit.
I will conclude with an outlook of future developments of single spin magnetometers for extreme conditions, such as high magnetic fields, mK temperatures or high-frequency sensors to probe the dynamics of nanomagnetic systems.
