Current Research Aim of our research is to find new materials with higher functionality. Our major effort is preparation, crystal structure determination and magnetic measurements of organic radicals, coordination polymers, and minerals. Recent studies are as follows:

(1) Hydrogen-Bonded Coordination Polymer for Spin-Proton Cooperative Systems
 
(2) Spin-frustration Systems Composed of Low-dimensional Copper Hydroxides with Organic Molecules
 
(3) Organic Molecule-based Magnetic Materials and their Molecular or Metal Complexes
 
(4) Molecular Clusters of Main Group Elements with Unpaired Electrons
