Colloidal synthesis of ultrathin KFeS₂ and RbFeS₂ magnetic nanowires with non-van der Waals 1D structures.

ABSTRACT: Design of one-dimensional (1D) nanomaterials based on non-van der Waals (non-vdW) 1D chain structures is emerging as a new materials frontier, owing to their strong intrinsic anisotropy and broad compositional diversity. However, achieving ultrathin 1D morphology in such systems remains a significant challenge. In this work, we report the colloidal synthesis of ultrathin KFeS₂ and RbFeS₂ nanowires-representing the first fabrication of ultrathin 1D nanomaterials driven by non-vdW 1D crystal structures. The nanowires exhibit diameters of ∼5 nm and lengths of microns, with anisotropic growth directed by covalent [FeS₂]^- chains. Magnetic characterization reveals significantly reduced antiferromagnetic transition temperatures and suppressed interchain
