Abstract
Nitrogen Vacancy (NV) centers in diamond have emerged over the past few years as well-controlled quantum systems, with promising applications ranging from quantum information science to magnetic sensing. In this talk, I will first briefly introduce the NV center system, as well as the experimental methods used for measuring them and controlling their quantum spin dynamics. I will then describe two recent experiments utilizing the magnetic sensing capabilities of NVs. Specifically, we measure the magnetization reorientation induced by chiral molecules adsorbed on the surface of a sample with a thin Cobalt layer, suggesting a persistent effect originating from strong exchange interactions. In addition, we image the spatial structure of magnetization in thin van-der-Waals magnets across the phase transition, providing insights into the dynamics of the magnetic domains across the transition.
