Synthesizing Kagome lattice FeGe Single Crystals

Letters & Science (College of) / Physics

Project Description

This project aims to grow FeGe single crystals and investigate their antiferromagnetic properties. FeGe can exist in several structural forms, and among them, the structure that hosts a Kagome lattice is known to be particularly difficult to grow as a single crystal. However, it has been reported that crystals of 1–2 mm in size can be grown using a method called chemical vapor transport. In this project, Aaron will work in our lab to synthesize this material. If successful, we will inspect the surface of the single crystals to select flat samples suitable for further experiments. Using a Laue X-ray machine, we will determine their crystallographic orientations. These samples will then be brought to the National Synchrotron Light Source II, where we plan to investigate the properties of antiferromagnetic domains and domain walls using advanced X-ray techniques.

Tasks and Responsibilites

The student will be involved in all stages of the FeGe synthesis process, including sample preparation and inspection. To support this work, they will receive training on how to use a powder X-ray diffractometer and a Laue X-ray camera. They will participate in data collection and analysis, and will be responsible for presenting his progress at our weekly group meetings. If the synthesis is successful and beamtime is granted, they may also have the opportunity to travel to the synchrotron facility to take part in the experiment during the academic semester.
