Anomalous CDW response in high mobility magnetic 2D material GdTe₃

Most known magnetic van der Waals (vdW) materials are insulating or semiconducting. It is crucial to find materials with magnetic order and high-mobility for high-speed spintronic device making. Anti-ferromagnet GdTe3 satisfies both down to 2D limits. It also exhibits an incommensurate charge density wave (CDW) but the role of it in GdTe3 properties is still unclear. Here, we report the recent temperature and polarization dependent Raman study of GdTe₃, we will talk about the coupling between CDW mode and the existing phonons.
