Nanoscale magnetometry with single spins

Patrick Maletinsky
University of Basel

Quantum two-level systems offer attractive opportunities for sensing and imaging at the nanoscale. In the fifteen years since its inception, this idea [1] has advanced from proof of concept [2] to a mature quantum technology [3], which already finds applications in condensed matter physics, materials science and beyond. In this talk, I will present the key engineering challenges [4] we have addresses in this development and highlight particularly rewarding scientific applications of single-spin, nanoscale magnetometry. I will focus on the field of antiferromagnetism and antiferromagnetic spintronics [5], to which we have introduced this technique [6-8], and discuss recent results where we addressed the nanoscale mechanics of antiferromagnetic domain walls.
