Local-Moment Ferromagnets - Markus Donath

. .

Résumé :
Some ferromagnetic materials with localized magnetic moments have become a hot topic of modern solid state physics because of their potential applications, e.g. in spintronic devices. The magnetic systems of interest comprise diluted magnetic semiconductors and half-metallic ferromagnets. Like conventional concentrated local-moment systems, they are characterized by an exchange interaction between localized magnetic moments and quasi-free charge carriers. The current research on local-moment ferromagnetism is reviewed in a tutorial style by leading experts in this field. Experimentalists present the latest approaches to characterize the unique material properties and theoreticians share decisive ideas to describe the observed phenomena theoretically. Students and researchers alike will benefit from this status report.

Biographie:
Prof. Nolting is an expert in solid state theory with emphasis on magnetism for many years (see his series on theoretical physics in Springer Verlag and his books on Quantentheorie des Magnetismus I,II in Teubner Verlag). Prof. Donath is an expert in experimental physics with emphasis on spin-resolved electron spectroscopies to study magnetic materials. (He has co-edited four books so far, two with Prof. Nolting).
