Pressure induced suppression of the singlet insulator phase in BaVS${}_3$: infrared optical study

I. Kézsmárki, G. Mihály, R. Gaál +5

The metal-insulator (MI) transition in BaVS${}_3$ has been studied at ambient pressure and under hydrostatic pressure up to $p=26$kbar in the frequency range of $20-3000$cm${}^{-1}$.…
