Quantum oscillations of the magnetic torque in the nodal-line Dirac semimetal ZrSiS

We report a study of quantum oscillations (QO) in the magnetic torque nodal-line Dirac semimetal $\mathrm{ZrSiS}$ fields up to 35 T and temperature range from 40 K down 2 K, enabling high resolution mapping Fermi surface (FS) topology ${k}_{z}=\ensuremath{\pi}$ (Z-R-A) plane first Brillouin zone (FBZ). It is found that oscillatory part measured signal consists low frequency (LF) contributions (frequencies 1000 T) (HF) (several clusters frequencies 7--22 kT). Increased angle-resolved measurements allow us show oscillation originate breakdown (MB) orbits involving individual $\ensuremath{\alpha}$ hole $\ensuremath{\beta}$ electron pockets diamond shaped FS Z-R-A plane. Analyzing HF we unequivocally QO dog-bone pocket ($\ensuremath{\beta}$ pocket) amounts $\ensuremath{\beta}=591(15)$ T. Our findings suggest most LF can also be explained by MB when intraband tunneling dog-bone-shaped taken into account. results give new understanding novel properties sister compounds.
