Study of the symmetry of electronic system of the Weyl semimetal GdBiPt using rotational anisotropy of second harmonic generation

Simon Daneau, Richard Leonelli, Andrea D. Bianchi

The half-Heusler compound GdBiPt orders antiferromagnetically around $T_{\mathrm{N}}=8.5$ K which implies breaking the time reversal symmetry as well as the translational symmetry. T…
