| Research Abstract |
Expermental as well as theoretical research on spin related phenomena in semiconductor quantum structures has been conducted in order to establish (1) fabrication processes of semiconductor quantum structures with pronounced spin effects.(2) understanding of the spin related phenomena in such structures, and (3) possible application of the semiconductor quantum structures using the new degree of freedom related to spin of electrons. Two Symposia named "Symposium on the Physics and Application of Spin-Related Phenomena in Semiconductors" were held at the Research Institute of Electrical Communication, Tohoku University on December 20-21,1995, and at the Sendai International Center on January 27-28,1997 in an effort to bridge the gap between the Semiconductor Materials and the Magnetic Materials. Following results are among those the research results obtained in the course of the present project.
(1) Epitaxial growth of magnetic materials on Si
(2) A new III-V based ferromagnetic diluted magnetic semiconductor, (GA,Mn)As
(3) Control of exchange interaction among magnetic ions by semiconductor nanostructures
(4) Experimental verification of the existence of free magnetic polarons
