From: Robust negative longitudinal magnetoresistance and spin–orbit torque in sputtered Pt3Sn and Pt3SnxFe1-x topological semimetal

Fig. 3

a, b The crystal structure of pristine Pt3Sn and the band structure of pristine Pt3Sn that shows weak topological features. Blue and red lines represent band structures with and without spin–orbit coupling, respectively. c Enlarged band structure with the Dirac nodes around the R point. d, e The crystal structure of pristine Pt3SnxFe1−x and its band structure that shows clear spin-splitting and formation of TRS-broken WSM. Blue, black (spin up), and red (spin down) lines represent band structures with/without spin–orbit coupling, respectively. f Enlarged band structure with the Weyl nodes around the R point that shows formation of TRS-broken WSM.
