Exploring consequences of Dirac nodal lines in ternary semimetal ZrSiS by angle-dependent magneto electrical transport measurements

ARPES, de Haas-van Alphen and Shubnikov de Haas quantum oscillation studies of ZrSiS have revealed that this ternary semimetal hosts Dirac nodal line fermions through the determination of a non-trivial Berry phase. Interesting behavior was observed in the magnetoresistance measurements including a butterfly-shaped angle dependence as the magnetic field is tilted away from the $c$ axis. We studied the consequences of Dirac line nodes in the electrical transport properties of this material by carrying out systematic angle-dependent magnetoresistance and Hall coefficient measurements. The effects of the existence of the zeroth Landau level when the field is aligned in the Dirac nodal line plane will be discussed.
