Novel electronic and magnetic materials research group
Our aim is to explore novel electronic and magnetic materials exhibiting unprecedented properties and to understand their underlying mechanisms.
We advance our research through a comprehensive approach from material synthesis to characterisation. In particular, we focus on the growing of high-quality single crystals. Images of several representative crystals that have been grown by ourselves are shown below.
Our current research interests include antiferromagnets with special symmetry, topological materials, and unconventional superconductors.
