Magnetic phase boundary of BaVS 3 clarified with high-pressure μ+SR
Abstract
The magnetic nature of the quasi-one-dimensional BaVS3 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, BaVS3 enters an incommensurate antiferromagnetic ordered state below the N e ´el temperature (TN)31 K . TN is almost constant as the pressure (p ) increases from ambient pressure to 1.4 GPa, then TN decreases rapidly for p >1.4 GPa , and finally disappears at p ∼1.8 GPa , above which a metallic phase is stabilized. Hence, TN is found to be equivalent to the pressure-induced metal-insulator transition temperature (TMI) at p >1.4 GPa .
