| Outline of Final Research Achievements |
We developed the spin-1/2 Kagome lattice antiferromagnet CaCu3(OH)6Cl2・0.6H2O (Ca-Kapellasite) which had the perfect Kagome lattice without an anti-site disorder. Theoretical studies have predicted the realization of the quantum spin liquid state in which the spin fluctuation survives even at T = 0. By measuring various physical properties of the single crystal of the compound, we found that the unconventional magnetic state was realized and the anomalous magnetic excitation underlay on the ground state of CaCu3(OH)6Cl2・0.6H2O.
