| Abstract Scope |
Materials that merge protected topologies with magnetism are emerging as reservoirs for intriguing phenomena, and substantial efforts have already been directed towards d-electron systems. Prominent examples include the (MnBi2Te4)•(Bi2Te3)n family and Kagome metals. Much less extensively studied are examples that include f-electron elements, despite these systems offering noteworthy opportunities. This includes that the f-shell is associated with localized magnetic moments, strong spin anisotropies, complex spin textures, and in some cases hybridization with the conduction electrons (e.g., through the Kondo interaction). In this talk I will discuss our progress studying the materials LnTAl4Ge2 (Ln = lanthanide and T = transition metal), which exhibit a rich combination of magnetic order, strong electronic correlations, and topological band structures. I will also examine prospects for introducing actinide elements into this structure, which is attractive for producing additional strongly correlated electron states. |
