Thermal Conductivity and Spin State of the Spin Diamond-Chain System Azurite Cu3(CO3)2(OH)2

Yuta Hagiya, Takayuki Kawamata, Koki Naruse +7

In order to investigate the spin state of azurite, Cu3(CO3)2(OH)2, we have measured the thermal conductivity along the c-axis, $\kappa$c, perpendicular to the spin diamond-chains. It ha…
