Control and local measurements of the spin chemical potential in a magnetic insulator Dr. Chunhui Du Postdoctoral Fellow, Department of Physics, Harvard University This lecture has been generously funded through The IBM Corporate Lecture Series, created to foster women's inclusion in science, technology, engineering and mathematics (STEM). In recent decades, a large scientific effort has focused on harnessing spin transport for providing insights into novel materials and low-dissipation information processing. We introduce single spin magnetometry based on nitrogen-vacancy (NV) centers in diamond as a new and generic platform to locally probe spin chemical potentials which essentially determine the flow of spin...
