Discovery of Honeycomb and Kagomé Quantum Magnets

ORAL  · Invited

Abstract

In this talk, I will present recent results on the discovery of kagome and honeycomb quantum magnets. Particular focus will be placed on the development of cobalt and rare earth based honeycomb materials, and the similarities and differences between integer and half-integer spin ions. The discovery of bidirectional twisting in MgCo6Ge6 will also be discussed and put in context. If time permits, I will also report on emerging materials discoveries that have the potential to reveal Kitaev spin liquid ground states.

*Work that will be discussed includes that supported by the Institute for Quantum Matter, an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Award DE-SC0019331, and the David and Lucile Packard Foundation. Use of the Advanced Photon Source at Argonne National Laboratory was supported by the U. S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-AC02-06CH11357. The 3He MPMS was funded by the National Science Foundation, Division of Materials Research, Major Research Instrumentation Program, under Award 1828490. Other work that might be discussed was supported of the Platform for the Accelerated Realization, Analysis, and Discovery of Interface Materials (DMR-1539918), a National Science Foundation Materials Innovation Platform. Access to the Bruker 1172 instrument was also possible via the Hopkins Extreme Materials Institute (HEMI). Calculations wer
