Juana Moreno discusses spintronics at SEM seminar Oct. 13 Juana Moreno, assistant professor of physics, will discuss her work, "Modeling of Ferromagnetic Semiconductors: Finding the Optimal Material Parameters for Spintronic Devices," as part of the School of Engineering and Mines Seminar series at noon Friday, Oct. 13, in 218 Harrington Hall. "Spin-based electronic (spintronic) devices utilize both carrier spin and charge to transmit or store information. Ferromagnetic semiconductors are ideal candidates for spintronic applications. Dr. Moreno's work focuses on developing a reliable theory of the magnetic, transport and optical properties of dilute magnetic semiconductors, such as GaMnAs. Since the successful design of spintronic nanostructures based on ferromagnetic semiconductors must include an understanding and careful analysis of disorder and spatial correlations, she also will discuss how these effects are included by using a new algorithm specific to dilute systems. Spintronics is one of two research clusters being supported under the current North Dakota EPSCoR Program. The University community is invited to attend. -- Wayne Seames, Associate Professor, Chemical Engineering, wayneseames@mail.und.edu, 777-2958
