Sažetak
The metal-insulator transition (MIT) of BaVS3 is suppressed under pressure, and above the critical pressure of p(cr)approximate to 2 GPa the metallic phase is stabilized. We present the results of detailed magnetoresistivity measurements carried out at pressures near the critical value in magnetic fields up to B=12 T. We found that slightly below the critical pressure the structural tetramerization-which drives the MIT-is combined with the onset of magnetic correlations. If the zero-field transition temperature is suppressed to a sufficiently low value (T-MI <= 15 K), the system can be driven into the metallic state by application of magnetic field. The main effect is not the reduction of T-MI with increasing B, but rather the broadening of the transition due to the applied magnetic field. We tentatively ascribe this phenomenon to the influence on the magnetic structure coupled to the bond order of the tetramers
