Research

High-quality and sizable single crystals are the foundation for exploring novel quantum phenomena and achieving exceptional functionalities. We employ techniques including floating-zone growth, flux growth, and chemical vapor transport to synthesize high-quality bulk single crystals of quantum materials. Our research interests span a broad range of material systems, including quantum magnets, multiferroics, strongly correlated oxides, and superconductors, with particular emphasis on uncovering emergent electronic and magnetic phenomena arising from the interplay between spin, charge, orbital, and lattice degrees of freedom.

We perform comprehensive in-house characterization of quantum materials using cryogenic measurement systems and investigate physical properties including magnetization, electrical transport, heat capacity, and dielectric response over wide temperature and magnetic-field ranges. In addition, we develop specialized devices and measurement techniques to probe functional behaviors in quantum materials, including magnetoelectric coupling, ionic mobility, domain engineering, and piezomagnetism. 

Neutron scattering is a powerful tool for probing magnetism. We travel with our single crystals to Oak Ridge National Laboratory and utilize neutron diffraction and inelastic neutron scattering techniques to investigate magnetic structures and spin excitations in quantum materials. The magnetic symmetry revealed by neutron diffraction can provide the foundation for discovering and understanding emergent phenomena such as multiferroicity and altermagnetism. Meanwhile, inelastic neutron scattering enables direct exploration of novel excitations including topological Dirac magnons and nonreciprocal magnons.
