Magnetic Materials Research

Research Overview

Our research focuses on the investigation of novel magnetic materials in the form of bulk ingots, single-crystalline films and nanostructured particles for permanent magnets, magnetic refrigeration, spintronic devices and biomedical applications. The primary goal of our research is to provide physics undergraduates with important research skills in materials synthesis and characterization, preparing them for quality graduate programs or industry jobs.
