Abstract
Single crystals of topological Dirac semimetal Cd3As2 were synthesized using a modified vapour transport technique. The magnetization of Cd3As2 single crystals was measured in the temperature range from 4.2-300 K and magnetic field up to 5 T along [001] and [100] directions. In the low temperature region we observed the de Haas van Alphen (dHvA) oscillations which allow us to characterize the three dimensional Fermi surface by extracting its relevant parameters. The dHvA oscillations show the existence of two different Fermi surface cross sections and nontrivial Berry’s phase, which is the signature of Dirac fermion in Cd3As2.
Highlights
Three-dimensional (3D) topological Dirac semimetals (TDS) have been theoretically predicted [1, 2, 3] and a crystalline-symmetry-protected 3D bulk Dirac semimetal phase has been experimentally identified in a high-mobility Cd3As2 single crystal using the angle-resolved photoemission spectroscopy (ARPES) [4, 5]
