Kagome lattice can host abundant exotic quantum states such as superconductivity and charge density wave (CDW). Recently, successive orders of A-type antiferromagnetism (AFM), CDW and canted AFM have been manifested upon cooling in kagome FeGe. However, the mechanism of CDW and interaction with magnetism remains unclear. Here we investigate the evolution of CDW with temperature across the canted AFM by single-crystal x-ray diffraction, scanning tunneling microscope (STM) and resonant elastic x-ray scattering (REXS). For the samples with longer annealing periods, CDW-induced superlattice reflections become weak after the canted AFM transition, although long-range CDW order is still detectable by STM and REXS. We explore a long-range CDW order with suppressed structural modulation. Additionally, occupational modulations of Ge1 in the kagome plane and displacive modulations of all atoms were extracted. The results confirm Ge dimerization along the c axis and suggest a dynamic transformation between different CDW domains.
Kagome materials have become a popular platform to investigate a range of competing quantum phases, such as the interplay between superconductivity and charge density waves (CDW). Here, the authors use x-ray diffraction, scanning tunneling microscopy and resonant elastic x-ray scattering to investigate the evolution of CDW ordering as a function of temperature in canted antiferromagnetic kagome FeGe. They find for post-annealed samples that the long-range CDW orders persist even as the structural modulations are suppressed although observations are highly dependent on the sample growth condition.
