Abstract
Spin correlation, competing interactions and subtle interplay between various degrees of freedom can lead to novel quantum states in correlated electron systems. Insights into the intrinsic magnetic susceptibility and the origin of complex magnetic ordering on a microscopic scale set an attractive setting in correlated quantum matter. In this context, Nuclear Magnetic Resonance (NMR) probe offers an unprecedented approach to explore the underlying physical mechanism of correlated quantum phenomena in condensed matter physics. NMR is a site selective microscopic technique extremely sensitive to low energy spin dynamics defining the ground state properties and is useful in mapping the tomography of correlated electron materials. NMR is a powerful microscopic probe to extract the intrinsic magnetic susceptibility and to probe topological order and elucidate the nature of enigmatic elementary excitations in correlated quantum matter. NMR shares an interface with muon spin relaxation (µSR) and neutron scattering and the combination of these techniques on a complementary scale provides an outstanding track to shed insights into the dynamics of dressed quasi-particles in the ground state of correlated electron materials. In this short review, we focus on some of the emergent physical phenomena in a few correlated electron materials sharing common experimental signatures in magnetization, specific heat, and NMR spin susceptibility and spin lattice relaxation rates. © 2019 Elsevier B.V.
