Presents "μSR and NMR as Probes of Correlated-Electron States"

Speaker: Dr. Oscar Bernal
Professor, Dept. of Physics and Astronomy

We present an overview of two spectroscopic techniques used to study magnetism in correlated-electron systems and their applications. Both Muon Spin Rotation μSR and Nuclear Magnetic Resonance NMR are local probes of static and dynamic magnetism. They probe and map out the magnetic field (its strength and magnitude variations in space and time: static and dynamic fluctuations) at the magnetic probe (muon or nucleus respectively), shedding light on the underlying mechanisms that produce interesting behavior in systems such as heavy-fermion materials, unconventional superconductors, and quantum magnets. A few examples of our studies in some of these systems will be
highlighted.
