Even in the form of two-dimensional-like ultrathin films, they exhibit a relatively high Curie temperature, magnetic anisotropy perpendicular to the atomic planes, and multiple types of Hall effects. We explore nanoribbons made from single layers of these materials and show that they display noncollinear magnetic ordering at their edges. This magnetic inhomogeneity allows angular momentum currents to generate magnetic torques at the sample edges, regardless of their polarization direction, significantly enhancing the effectiveness of maNano lettersNoncollinear Edge Magnetism in Nanoribbons of Fe<sub>3</sub>GeTe<sub>2</sub> and Fe<sub>3</sub>GaTe<sub>2</sub>.PMC12333401317320/2021-1E-26/200.240/2023E-26/205.957/2022 (282056)E26/200.240/2023Bergman AStrand HURMuniz RBCardias RCosta MfalseNoncollinear Edge Magnetism in Nanoribbons of Fe<sub>3</sub>GeTe<sub>2</sub> and Fe<sub>3</sub>GaTe<sub>2</sub>.Fe₃GeTe₂ and Fe₃GaTe₂ are ferromagnetic conducting materials of van der Waals type with unique magnetic properties that are highly promising for the development of new spintronic, orbitronic, and magnonic devices.
