| Popis: | We present results of high-resolution thermal expansion at low temperature in (TMTSF) 2 PF 6 along the a -axis. Within our sensitivity ( Δl / l ∼ 10 −8 ), no anomaly is present at the metal-to-insulator transition at 13.7 K. A power-law analysis shows that the main contribution to the thermal expansion arises from phonons. The observed magnetostriction being very small, we conclude from all the measurements that the coupling between the antiferromagnetic order (in the insulator phase) and the a -axis is very weak. |
