Project Description
This research aims to study a complex behavior of antiferromagnetic domains in Fe1-xCoxSn (x ~ 0.06) that appears in different temperature cycles. The antiferromagnetic transition in this compound is a smooth and continuous second-order transition that should behave the same way during warming and cooling. However, we observed in our preliminary measurements that the antiferromagnetic domains form significantly different between cooling and warming. The mechanism of such behavior is unknown and is the center of this research. We will employ the direct space and real-time coherent soft X-ray imaging technique and study the formation of antiferromagnetic domains in temperature and associated domain dynamics in temperature. The PI developed this technique in 2018 and actively employed it to study antiferromagnetic domains and domain walls.
Tasks and Responsibilites
The student has spent the last two semesters in our lab and gained experience growing materials and characterizing them using our powder X-ray diffractometer. He will help grow Fe1-xCoxSn single crystals and prepare them for imaging experiments. Imaging experiments will take place at the National Synchrotron Light Source 2 (NSLS-2) at the Brookhaven National Laboratory. The student is required to participate in the experiment at NSLS-2. After the experiment, the student will learn how to use the program language Python and analyze the image data.
