Shubnikov de Haas oscillations and magnetic properties of p type polycrystalline ZrTe<sub>5</sub>
POSTER
Abstract
We report the magnetoresistance and magnetic properties of the polycrystalline p-type ZrTe5. We observed Shubnikov de Haas (SdH) oscillations in the compound with the small cyclotron effective mass of ~ 0.05me and high mobility of ~ 2.2 × 104 cm-2/V-s. Magnetoresistance data shows three dimensional Weyl semimetal like behavior. Kohler’s rule is obeyed at low temperatures ≤ 10K. The fast Fourier transform analysis of SdH oscillations show a single predominant oscillation frequency. The paramagnetic peak in M/H versus H data extends in broad field range up to 4 Tesla at 1.8 K, field range and size of peak decreases with increasing temperature. We have compared our results on p-type polycrystal with bipolar single crystal ZrTe5 reported in the literature.
