Magnetotransport properties in van der Waals RTe3 (R=La, Ce, Tb)

Rare-earth tritellurides are van der Waals antiferromagnets that are a promising platform not only for spintronic devices but also for the study of the correlation between the charge density wave (CDW) and magnetic states in low-dimensional materials. Here, the authors perform longitudinal and Hall resistivity measurements in exfoliated $R$Te${}_{3}$ ($R$=La, Ce, Tb) thin film devices. The carrier mobility and concentration change at the magnetic transition temperature. The result suggests the strong coupling between the CDW and antiferromagnetic phases.
