Abstract

We carried out magnetotransport experiments under hydrostatic pressure in order to study the nature of the metal-insulator transition in BaVS3. Scaling relations for ρ(T,H,p) are established and the pressure dependence of the spin gap is determined. Our results, in conjunction with a reanalysis of earlier specific-heat and susceptibility data, demonstrate that the transition is weakly second order. The nature of the phase diagram in the T-p-H space is discussed.
