Fig. 1: Symmetries and topology for out–of– and in–plane magnetic field in Co3Sn2S2.
From: Generation of a nodal line and Weyl points by magnetization reorientation in Co3Sn2S2
The first row (a, d, g) shows a real-space representation of the magnetization for M⊥a, M∥c and M∥a. The second and third rows show a top and 3D view of the corresponding BZ for the respective configuration. a–c Inequivalent nodal loops (NL1/2) and emerging Weyl points (WP) for M⊥a. Those have the same color as their corresponding loop or are dark blue if located at other k points. d–f Three equivalent nodal loops related by the C3 rotational symmetry for out--of--plane magnetization. g–i Mirror plane protected nodal loops for M∥a highlighted by thick orange lines.
