Observation of large nonsaturating magnetoresistance in rare-earth monopnictides has raised enormous interest in understanding the role of its electronic structure. Here, by a combination of molecular-beam epitaxy, low-temperature transport, angle-resolved photoemission…

Trivial to nontrivial topology transition in rare-earth pnictides with epitaxial strain
The combination of magneto-transport and topological properties has brought great attention to rare-earth mono-pnictides semimetals. For some of them, like LaSb, it is unclear whether they show


Separation of electron and hole dynamics in the semimetal LaSb
We report investigations on the magnetotransport in LaSb, which exhibits extremely large magnetoresistance (XMR). Foremost, we demonstrate that the resistivity plateau can be explained without

The family of binary Lanthanum monopnictides, LaBi and LaSb, have attracted a great deal of attention as they display an unusual extreme magnetoresistance (XMR) that is not well understood. Two
Temperature−field phase diagram of extreme magnetoresistance
It is suggested that XMR in LaBi and LaSb originates from a combination of compensated electron−hole pockets and a particular orbital texture on the electron pocket, which is likely to be a generic feature of various topological semimetals, giving rise to their small residual resistivity at zero field and subject to strong scattering induced by a magnetic field.

The existence of surface states of LaBi is revealed through the observation of three Dirac cones: two coexist at the corners and one appears at the centre of the Brillouin zone, by employing angle-resolved photoemission spectroscopy in conjunction with ab initio calculations.
Fermi surface topology and magnetotransport in semimetallic LuSb
A comprehensive investigation of Fermi surface and electrical transport properties of LuSb, another representative of this family of rare-earth monopnictides, finds that the FermI surface of this compound consists of several pockets originating from fairly compensated multi-band electronic structure, in full accordance with first-principles calculations.
