Half metallic ferromagnets.
Since its introduction by de Groot and colleagues in the early 1980s [1], the concept of half metallic ferromagnetism has attracted great interest. Idealized, half-metals have only one spin channel for conduction: the spin-polarized band structure exhibits metallic behavior for one spin channel, while the other spin band structure exhibits a gap at the Fermi level. Due to the gap for one spin d...
متن کاملHalf-metallic Zinc-Blende Compounds
We report first-principles calculations of zinc-blende half-metals, identifying systems for epitaxial growth with semiconductors, and present calculations for CrAs/GaAs multilayers. We find that half-metallicity is conserved troughout the heterostructure, making this a good candidate for spintronics applications.
متن کاملHalf - metallic Armchair Graphene Nanoribbon
Submitted for the MAR10 Meeting of The American Physical Society Half-metallic Armchair Graphene Nanoribbon FUMIYUKI ISHII, KEISUKE SAWADA, MINEO SAITO, Kanazawa University — Among a variety of applications of graphenes, spintronics applications are considered to be hopeful. For an example, spin transport has been experimentally observed by using graphene layers [1]. There are two types of shap...
متن کاملMagnetoresistance of Half-Metallic Oxide Nanocontacts
Magnetoresistive effects R 0 -R H R H exceeding 500% are found at room temperature in a field of 7 mT in nanocontacts between Fe3O4 crystallites. The shape of the I V curve depends on field and the magnitude of the magnetoresistance is correlated with the resistance, the largest effects occurring when R . 100 kV. The explanation proposed involves hopping transport of spin-polarized electrons th...
متن کاملHigh-pressure structure of half-metallic CrO2
Evidence for a structural phase transition from rutile -CrO2 phase I P42/mnm to orthorhombic -CrO2 phase II CaCl2-like, Pnnm is presented using angle-resolved synchrotron x-ray diffraction and highsensitivity confocal Raman spectroscopy. The transition to the CaCl2 structure, which appears to be second order, occurs at 12±3 GPa without any measurable discontinuity in volume, but is accompanied ...
