Popis: | CuCl2 graphite intercalation compounds (GICs) having CuCI2 magnetic intercalate layers are expected to give novel magnetic layer effect on their transport phenomena, through the π-d interaction. We investigate the transport properties of stage 1–4 CuCl2 GICs by means of c-axis magnetoresistance (MR) and thermoelectric powers. In stage-1 compound, anomalously large MR is observed for the field perpendicular to the c-axis, indicating a remarkable difference in the magnetic field direction dependence from that of in-plane MR governed by the cyclotron motion of the carriers. This implies the important role of the magnetic layers in the c-axis hopping process. The c-axis thermoelectric power shows an anomalous change around 70–100 K where a short range order hump appears in the magnetic susceptibility. |
