@article{Wang2016EvidenceOB, title={Evidence of both surface and bulk Dirac bands in ZrSiS and the unconventional magnetoresistance}, author={Xuefeng Wang and Xingchen Pan and Ming Gao and Jihai Yu and Juan Jiang and Junran Zhang and Huakun Zuo and Minhao Zhang and Zhongxia Wei and Wei Niu and Zhengcai Xia and Xiangang Wan and Yulin Chen and Fengqi Song and Yongbing Xu and Baigeng Wang and Guanghou Wang and Rong Zhang}, journal={arXiv: Materials Science}, year={2016} }

The unconventional magnetoresistance of ZrSiS single crystals is found unsaturated till the magnetic field of 53 T with the butterfly shaped angular dependence. Intense Shubnikov-de Haas oscillations resolve a bulk Dirac cone with a nontrivial Berry phase, where the Fermi surface area is 1.80*10^-3 A-2 and reaches the quantum limit before 20 T. Angle resolved photoemission spectroscopy measurement reveals an electronic state with the two-dimensional nature around the X point of Brillouin zone…
