Graduate student Kevin Smith and Professor Janice Musfeldt were recently featured by Lawrence Berkeley National Laboratory for their work with the Advanced Light Source (ALS). The highlight described the work in their paper entitled “Real-Space Infrared Spectroscopy of Ferroelectric Domain Walls in Multiferroic h-(Lu,Sc)FeO3” published in ACS Applied Matter Interfaces.
Smith and Musfeldt used infrared light from the ALS to investigate the properties of the domain walls that separate electrically polarized regions in a rare-earth ferrite material. Their findings open the door to broadband imaging of physical and chemical heterogeneity in ferroics, and improved understandings of the properties of flexible defect states. The complete highlight is available here.
