Magnetotransport evidence of a potential low-lying Dirac node in NbAl${}_3$

Ying Kit Tsui, Chia-Nung Kuo, Makoto Shimizu +5

NbAl${}_3$ is a novel semimetal with a type-II Dirac node ~230 meV above the Fermi energy. We have performed both out-of-plane ($B\parallel c$) and in-plane magnetotransport measurem…
