Neutron scattering as a probe of heavy transition metal magnetism

 

Unique paradigms of magnetism often arise from 4d and 5d transition metal-based magnets, which are an exciting family of quantum materials, due to a combination of strong spin-orbit coupling and spatially-extended d orbitals. Neutron scattering is a very powerful probe of the magnetism in these systems. In this talk, I will first introduce the technique of neutron scattering and the suite of instruments available through the user program at Oak Ridge National Laboratory to study quantum materials. I will then discuss some recent examples from my own research to highlight how neutron scattering can be used effectively to study the new phenomena and exotic magnetic ground states and excitations inherent to heavy transition metal magnets.  

 

Adam Aczel is currently a staff scientist in the Neutron Sciences Directorate at Oak Ridge National Laboratory and an assistant professor in the Department of Physics and Astronomy at the University of Tennessee as part of the Joint Faculty Program. Adam received a Ph.D. degree in physics from McMaster University in 2010. After graduation, he became a postdoctoral fellow in the Neutron Sciences Directorate before moving to his current positions. Adam’s research interests include neutron scattering and muon spin relaxation studies of quantum materials, with a current emphasis on frustrated magnetism, skyrmions, and heavy transition metal magnets. For Adam’s research contributions to elucidating proximate Kitaev spin liquid behavior in the quasi-2D magnet alpha-RuCl3, he received the UT Battelle Team Research Award and the UT Battelle Director’s Team Research Award in 2016.
