BROOKINGS Four undergraduate students in South Dakota State Universitys Department of Chemistry, Biochemistry and Physics attended the American Physical Societys annual meeting March 3-8 in Minneapolis, Minnesota.
Cole Brown, Gavin Baker, Matthew Wieberdink and Jax Wysong all physics majors presented their research on Heusler alloys, with Wieberdinks poster being recognized as an outstanding presentation by the American Physical Society. The quartets research is under the direction of Parashu Kharel, an associate professor of physics in SDSUs College of Natural Sciences.
Wieberdrink, a junior, presented his research on the crystalline and magnetic properties of Cr2MnAl a Heusler compound during the conferences poster session. The session was three hours long, and Wieberdink spoke for almost 2 1/2 hours of the allotted time. The interest in Wieberdinks work stems from the growing interest in the field of material sciences, Kharel noted.
While the poster session was illuminating, Wieberdinks biggest takeaway from the conference was the networking opportunities available, which resulted in him landing a competitive internship at Los Alamos National Lab through their Science Undergraduate Laboratory Internships program. He will work with the biotechnology group at Los Almos.
Baker, a senior, presented on his research, titled Effect of Mn Doping on the Magnetic and Electronic Band Properties of CoFeVAl: Experiment and Theory, which looks at the characteristic properties, both experimentally and computationally, of CoFeVAl, a type of Heusler alloy.
The application of this research is in spintronic technologies, Baker said.
The goal of this research is to find an alloy that would allow electronic devices, such as computers and phones, to require less battery power with improved speed.
This was Bakers second time presenting on site at this conference. His past experience helped in his preparation for this years conference.
The previous year, Baker learned that the questions from other researchers and presenters can be quite challenging.
When you talk about research to your family, they dont really know how to ask a challenging question, Baker explained. But when I talk about my research to people with Ph.D.s or with people who study physics, they know how to ask questions that might stump me. I need to be prepared to think through those.
For Brown, a first-timer at the conference, the level of the research was a bit surprising.
The variety of the research really surprised me, Brown said. They even had Nobel laureates present.
Browns oral presentation was on structural and magnetic properties of V2CoAl Heusler alloys.
Overall, the conference is eye-opening, Baker said.
Jax Wysong, a senior, presented at the conference for the second time as well.
His research shows how the change in stoichiometry affects the structural and magnetic properties of NiFeMnAl, a predicted half-metal. He has been awarded SDSUs 2024 Schultz-Werth Award for his work.
The American Physical Societys annual meeting is one of the most well-attended physics conferences in the world, with more than 13,000 physicists and students presenting their research.
