The recent discovery of extreme magnetoresistance in LaSb introducedlanthanum monopnictides as a new platform to study topological semimetals(TSMs). In this work we report the discovery of extreme magnetoresistance inLaBi, confirming lanthanum monopnictides as a promising family of TSMs. Thesebinary compounds with the simple rock-salt structure are ideal model systems tosearch for the origin of extreme magnetoresistance. Through a comparative studyof magnetotransport effects in LaBi and LaSb, we construct a triangulartemperature-field phase diagram that illustrates how a magnetic field tunes theelectronic behavior in these materials. We show that the triangular phasediagram can be generalized to other topological semimetals with differentcrystal structures and different chemical compositions. By comparing ourexperimental results to band structure calculations, we suggest that extrememagnetoresistance in LaBi and LaSb originates from a particular orbital textureon their qasi-2D Fermi surfaces. The orbital texture, driven by spin-orbitcoupling, is likely to be a generic feature of various topological semimetals.
