Pressure-induced suppression of the spin-gapped insulator phase in BaVS3: an infrared optical study
- The metal-insulator transition in BaVS3 was studied at ambient pressure and under hydrostatic pressure up to p=26kbar in the energy range of 2.5–500meV. The charge gap determined from the optical reflectivity was enhanced, Δch(p)∕kBTMI(p)≈12. This ratio is independent of pressure, indicating that the character of the transition did not vary along the p−T phase boundary. Above the critical pressure, pcr∼20kbar, metallic spectra were recorded in the whole temperature range, as expected from the shape of the phase diagram.
