Abstract
The ground state of the Mott-Hubbard insulator (TMTTF)(2)PF6 is known to va ry from Spin-Peierls (SP) at ambient pressure to antiferromagnetic (AF) wit h increasing pressure. Near 0.9GPa, the phase boundary of both SP and AF dr ops singularly to less than 9K. We interpret this result as the system is p ressure-tuned near a quantum critical point.
