Abstract
Kagome lattice materials are a compelling subject in condensed matter physics due to their unique geometry, which supports exotic quantum states, including flat bands, Dirac-like dispersions, and topologically nontrivial phases. This research focuses on the synthesis and preliminary characterization of the Kagome lattice compound HfFe6Ge6, known for its magnetic and electronic properties. Under the guidance of Professor Na Hyun Jo, the study began with an extensive review of the compound’s structural and electronic attributes, including its phase diagram and crystallographic data. Using a combination of binary and ternary phase diagrams generated in Wolfram Mathematica and data from the ICSD database, the optimal starting composition for crystal growth was determined as (Fe37Ge63)98Hf2. Following precise mass calculations and crystal growth procedures, the compound was synthesized via high-temperature solid-state reaction in an argonsealed quartz tube. X-ray diffraction (XRD) analysis confirmed the successful formation of HfFe6Ge6, aligning with the expected crystallographic phase. Future work involves preparing the sample for measurements using the Physical Property Measurement System (PPMS). These will include resistivity as a function of temperature to determine the crystal’s metallic behavior and purity, magnetoresistance against magnetic flux density, and an analysis of the Anomalous Hall Effect to explore its electronic transport properties. The outcomes aim to contribute to the understanding of Kagome lattice systems and their potential applications in quantum materials research.
