Spin dynamics of quantum spin liquid state in CaCu3(OH)6Cl2・0.6H2O
Recently we have succeeded in synthesizing a new kagome material, CaCu3(OH)6Cl2 0.6H2O. Single crystal X-ray measurements revealed that no site disorder between Ca and Cu sites... -
Inelastic neutron scattering study on CeMnAsO and LaMnAsO
RMnAsO (R = Ce and La) are isostructural compounds with Fe-based oxypnictides, but has a unique properties as Mott insulator unlike the nonsuperconducting parent compounds of... -
Magnetic excitations of SrV10O15
Recently, new type of frustrated magnets, BaV10O15 and SrV10O15, were found to exhibit interesting phenomena due to mixed valence ions forming a modified triangular lattice....
