The layered material ZrTe5 has been demonstrated to be a Dirac semimetal, according to recent ARPES and magneto-infrared spectroscopy experiments. While a direct transport evidence for Dirac semimetal phase in ZrTe5 is still lacking. Using the Steady High Magnetic Field Facilities (SHMFF) with a magnetic field up to 31 T and temperature down to 0.3 K, the group led by TIAN Mingliang, High Magnetic Field Laboratory, Chinese Academy of Sciences (CHMFL), carries out a detailed transport study on ZrTe5 nanoribbons and gives a clear transport evidence for Dirac semimetal phase in ZrTe5.
