Solid State Physics IV i V year of studies

Second semester 2006/07

Diluted Magnetic Semiconductors (DMS)

The course (2 hours a week) deals with unusual optical and magnetic properties of DMS, both in their bulk form and in quantum structures. These properties result from ion-carrier and ion-ion interactions, characteristic for this class of semiconductors. Diluted magnetic semiconductors are of fundamental importance for the emerging field of spintronics.

Program of the course contains:

• Idea and beginnings,
• Carrier-ion sp-d interaction and giant magnetooptic effects in bulk crystals
• Ion-ion d-d interaction and its experimental determination
• Mean field approximation for quantum structures, interface profiles (spin tracing)
• Role of magnetic fluctuations
• Influence of carriers on magnetic properties of bulk crystals and quantum structures
