The Holcomb team has discovered a new type of magnetization that is easily switchable, the magnetoelectric dead layer and methods for improving reliability in NASA's next generation single photon detectors. We focus on high quality growth and characterization of thin films exploiting techniques that are ideal for the study of surface and interfacial effects. For example, second harmonic generation (SHG), sensitive to both electric and magnetic fields at interfaces, is a perfect tool to monitor magnetoelectric, magnetic competition and other novel behaviors. Another powerful technique we utilize is x-ray absorption spectroscopy that allows element specific measurements of atomic valence and magnetization. The element specificity allows the study of multiple material layers and interfaces, also permitting the study of coupling in multilayered materials. We are also interested in utilizing machine learning to complement our experimental efforts.
