Oscillatory Behaviour of Magnetoresistance and Hall Effect of NbSe 3 up to 28 Tesla

Abstract
We report resistivity and Hall-coefficient measurements at very low temperatures (down to 70 mK) and very high fields (up to 28 tesla) of the one-dimensional metallic compound NbSe3. Hall effect displays quantum oscillating behaviour equivalent to the Shubnikov-de Haas oscillations of the resistivity. Weak hysteresis is observed in the whole range of magnetic field, between increasing and decreasing B, in the resistance oscillations. A larger hysteretic effect occurs near 20 tesla and appears in both resistivity and Hall coefficient.
