Opis

Half-metals are particular ferromagnetic materials which can be considered as hybrids between metals and semiconductors. A particular feature of these materials is that electrons at the Fermi level show complete spin polarization making them prime targets for research into suitable divices for spin electronics. This book is both an introduction and state-of-art survey of the latest advances in the understanding and applications of Heusler alloys and related compounds.
