The quasi-one-dimensional (Q1D) materials, (Per)2M(mnt)2, have transition temperatures of 12 and 8 K for M = Au and Pt, respectively, as samples are cooled from a metallic state to an insulating, charge density wave (CDW) ground state. In these proceedings, we present results regarding the effect of quasi-hydrostatic pressure and high magnetic fields on the CDW and field-induced density wave (FIDW) states of these materials. With pressures greater than 4 kbar, Shubnikov de Haas oscillations appear in the M = Au compound, which reach the n=1 Landau level before the limit of the applied magnetic field. While lower field (B < 20 T) results are similar for M = Pt, the FIDW state persists in higher fields, even under 5.3 kbar of pressure.
