Temperature−field phase diagram of extreme magnetoresistance
Abstract
Extreme magnetoresistance (XMR) has been recently discovered in a number of seemingly unrelated materials with diverse crystalline and electronic structures. In this work, we use lanthanum monopnictides, LaBi and LaSb, as simple platforms to reveal a common triangular Temperature–field phase diagram for XMR. Further, we show that, in the electronic structure of both materials, lanthanum d orbitals mix with the pnictogen p orbitals. Remarkably, we find that both the triangular phase diagram and the orbital texture exist in all families of semimetals with XMR. These results show that XMR is a ubiquitous phenomenon with a universal phase diagram that goes beyond certain material specifications; it is not a rare commodity of topological materials or noncentrosymmetric structures.
