Spin Interactions and Spin Dynamics in Electronic Nanostructures

This multidisciplinary research project was concerned with the development, understanding and application of powerful techniques for the manipulation and study of spin systems, the fabrication and study of interacting spin assemblies, and the study, characterization and application of spin transfer effects and of nanomagnet dynamics excited by spin polarized currents. Major accomplishments achieved during this project include the development and application of new tools and innovative techniques for the manipulation and study of spin phenomena in semiconductor systems, and other spintronics materials of technological importance, and the spectroscopic study of the spin transport properties of nanoscale systems, the demonstration of terahertz spin control in magnetic semiconductor quantum wells, the study of spin transport in single molecule devices, and the manipulation and successful study and understanding of individual spin-spin interactions in semiconductor surfaces. Major advances were also made in the understanding, development and enhancement of methods for the spin-transfer switching of nanomagnets for high density current addressable MRAM applications, and in the understanding and development of nanomagnet microwave oscillators for future information processing applications.
