Arjun Pathak, assistant professor of physics, published the peer-reviewed scientific article “Anomalous Electrical Transport Behavior in the Vicinity of the First-Order Magnetostructural Transition in the Giant Magnetocaloric Gd4ScGe4” in the American Physical Society journal Physical Review B 105, 174440 (2022). This work was in collaboration with Ames Laboratory, a national laboratory of the U.S. Department of Energy. The materials that undergo the first-order phase transformation usually show unusual physical properties that are often important for green energy applications. In this article, the authors reported a strong discontinuous first-order nature of the coupled magnetic and structural phase transition and an understanding of the electrical properties as a function of applied temperature and magnetic fields of the Gd4ScGe4 compound. The article provides a detailed understanding of the electrical and magnetic properties of rare-earth-based compounds.
