Abstract

We report inter-plane (R_zz) electrical transport measurements in the \tp series of organic conductors at very high magnetic fields. In the field range between 36 and 60 T R_zz shows a very hysteretic first order phase transition from metallic to an insulating state. This transition does not affect the Shubnikov-de-Haas oscillations associated with the two-dimensional (2D) Fermi surface. We argue that this transition originates from inter-plane disorder which gives rise to incoherent transport along the least conducting axis. We conclude that this system becomes a strictly 2D Fermi-liquid at high magnetic fields.
