Research Abstract

We have investigated nuclear magnetic resonance, NMR, capable to detect electron orbital motion in atomic resolution. Although conventional NMR technique has been limited in measurements of nonmagnetic insulators and metals, we have succeeded to probe directly electron orbitals using magnetic transition metal nuclear sites for magnetic materials. Our microscopic observations of orbital- and site-selective metal-insulator transitions in vanadates provide important progress for understanding strongly-correlated electron physics.
