Abstract

The magnetic nature of the quasi-one-dimensional ${BaVS}_{3}$ has been studied as a function of temperature down to 0.25 K and pressure up to 1.97 GPa on a powder sample using the positive muon spin rotation and relaxation ( $μ^{+} SR$ ) technique. At ambient pressure, ${BaVS}_{3}$ enters an incommensurate antiferromagnetic ordered state below the $N \overset{́}{e} el$ temperature $(T_{N}) 31 K$ . $T_{N}$ is almost constant as the pressure ( $p$ ) increases from ambient pressure to 1.4 GPa, then $T_{N}$ decreases rapidly for $p > 1.4 GPa$ , and finally disappears at $p \sim 1.8 GPa$ , above which a metallic phase is stabilized. Hence, $T_{N}$ is found to be equivalent to the pressure-induced metal-insulator transition temperature ( $T_{MI}$ ) at $p > 1.4 GPa$ .
