DOI: 10.1073/pnas.2208505119
Abstract: Significance The large linear positive magnetoresistance (LPMR) is widely observed in emergent topological materials. Various explanations, including linear band structure, impurity scattering, guiding center motion, or internode scattering, have been proposed. However, experimentally, this phenomenon… read more here.

DOI: 10.1103/physrevb.99.195111
Abstract: We report the discovery of a novel giant magnetoresistance (GMR) phenomenon in a family of BaMn$_{2}$Pn$_{2}$ antiferromagnets (Pn stands for P, As, Sb, and Bi) with a parity-time symmetry. The resistivities of these materials are… read more here.
