Shubinikov de-Hass van Alphen Oscillation and magnetic properties of p-type polycrystalline ZrTe5.
We report the magnetoresistance (MR) and Shubnikov de Haas (SdH) oscillations in the polycrystalline p-type ZrTe5. We observed a small cyclotron effective mass (m*~0.05me), very high mobility of 2.2 x 10^4 cm^2/V-s and the signature of topological protected surface states in the compound. The MR data follows the three dimensiional Weyl semimetal like behavior. Kohler's rule is obeyed at low temperatures. SdH oscillations show a single predominant oscillation frequency in fast Fourier transform spectra. The magnetic data supports the existence of topological surface states showing zero cusp paramagnetic susceptibility.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
