概要

• 論文の詳細を見る

• The metal-insulator transition (MIT) in the thiospinel Cu_<1-x>Zn_xIr_2S_4 has been investigated by means of ^<63>Cu NMR. We find that the sample with x = 0.3, having a uniform metallic phase at room temperature, exhibits a phase separation into the metallic and insulating regions below T_<MI> ~70 K, where the first order MIT is observed In the resistivity data. The insulating regions have the same Cu Knight shift as that in the diamagnetic insulator at x = O. This indicates that the charge density in the low-T insulating phase is invariant, which causes the carriers introduced by the Zn substitution to be segregated from the insulating regions. Based on these observations, a possible mechanism of the MIT is discussed.
