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 desired properties of the synthesized materials for a specific application are displayed in the poster below. 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.
