- 요약Topological semimetals (TSMs) are a class of materials of recent interest for their ability to host robust electronic states in which electrons move with exceptionally high mobility and low effective mass, such that their behavior is analogous to other particles typically restricted to the realm of high-energy physics. Materials containing a square net structure have been found to frequently host these topological phases, as a consequence of their crystal symmetry, making them a unique playground to explore the interaction of these topological states with other coincident properties, such as magnetism. This thesis comprises a survey of the synthesis, crystallography, and magnetic properties of the square-net TSM family LnSbxTe2−x−δ , across a wide range of Ln and x. Chapter 1 introduces band theory as it pertains to the electronic structure of topological semimetals, charge density wave (CDW) distortions, and square net materials. This provides the foundation to discuss the solid solution LnSbxTe2−x−δ (Ln= Lanthanide, δ= vacancy) as a family of TSMs which exhibit compositionally tunable band filling, CDWs, and magnetic states, offering a broad composition to explore the interplay of topological electronic states, CDW, and magnetism, while introducing the advanced crystallographic techniques vital to their study. Chapter 2 comprises a systematic structural study of the evolving CDW in CeSbxTe2−x−δ , in which an understanding of the structural distortions proves critical to understanding the unique magnetic phenomena across the series and establishing CDWs as a tool to engineer ideal topological materials. Chapter 3 further explores the interplay between magnetism and CDW in these compounds through NdSbxTe2−x−δ , where combined x-ray and neutron diffraction studies elucidate a coupling relationship between the CDW and an exotic magnetic structure containing an elliptical cycloid, the most direct observation of this coupling to date. Chapter 4 investigates the synthetic limits of LnSbxTe2−x−δ , summarizing attempts to synthesize phases across the entire range of Ln and x, applying our understanding of the structural chemistry of the family to build a stability phase diagram and introduce the synthesis of novel mixed Ln phases.
