  The Per2M(mnt)2 class of organic conductors exhibit a charge density wave
(CDW) ground state below about 12 K, which may be suppressed in magnetic fields
of order 20 to 30 T. However, for both cases of counter ion M(mnt)2 species
studied (M = Au (zero spin) and M = Pt (spin 1/2)), new high field ground
states evolve for further increases in magnetic field. We report recent
investigations where thermopower, Hall effect, high pressure and additional
transport measurements have been carried out to explore these new high field
phases.
