Abstract
The four-probe method was used to measure the electrical resistivity and transverse magnetoresistance of stage-2 MnCl 2GIC. Both the in-plane and c-axis resistivity were measured in the temperature range between 298 and 12 K. The in-plane resistivity was found to be metallic. This behavior was observed for most GICs. The c-axis resistivity was found to decrease with decreasing temperature, which is a typical behavior for low stages of acceptor compounds of graphite. The in-plane and along the c-axis transverse magnetoresistance were measured in the low magnetic field limit (up to 5 kG) at temperatures 298, 77 and 12 K. The average mobility was calculated from the data of the magnetoresistance assuming a simple two-band model.
