The interplay between charge-density wave order and magnetism has been a prominent area of research for decades, encompassing unconventional superconductors to more recent Kagome metals. The cooperative or competitive nature of these two phenomena has been a fundamental aspect of many-body physics. Recently, it has been demonstrated that RTe3 (R = rare earth) van der Waals materials exhibit helimagnetic textures coupled to an unconventional charge-density wave order. Here, we review recent developments in one of the ultra-clean members of the series, DyTe3. We reveal further evidence for the unconventional spin-charge coupling in this material by combining magnetic, transport and neutron scattering measurements.
