C-axis resistance of stage 2 SbCl5 intercalated graphite under pressure

• The c-axis resistance R of stage 2 SbCl5 intercalated graphite has been measured in the range 80–300 K and 0–4 GPa. The pressure dependence of R is similar to that of HOPG in the ordered low-T phase below 200 K but significantly larger at 300 K, where the initial pressure coefficient of R is −1.37 GPa−1. Two phase transitions are always observed under pressure, one at 0.3–0.5 GPa and one above 1 GPa. The latter is not completed until above 2.4 GPa and both are slow, with large time-dependent effects in R. R decreases by over 80% to 4 GPa.
