Half-metallic alloys: electronic structure, magnetism and spin polarization.
Using the state-of-the-art screened Korringa-Kohn-Rostoker Green function method we study the electronic and magnetic properties of NiMnSb and similar Heusler alloys. We show that all these compounds are half-metals, e.g. the minority-spin band is semiconducting and the Fermi level falls within this gap resulting in 100% spin polarization at the Fermi level. The total spin moment M(t) shows the...
متن کاملHalf-metallic ferromagnetism of MnBi in the zinc-blende structure
The full-potential augmented plane wave plus local orbital method within density-functional theory is used to predict that MnBi in the zinc-blende structure is a true half-metallic ferromagnet with a magnetic moment of 4.000mB per formula unit. This contrasts with the zinc-blende phase of MnAs, which is only a nearly half-metallic ferromagnet. This half-metallic ferromagnetic behavior of zinc-b...
متن کاملEffects of three-dimensional band structure in angle- and spin-resolved photoemission from half-metallic La2Õ3Sr1Õ3MnO3
We present an angleand spin-resolved photoemission study of half-metallic three-dimensional perovskite La2/3Sr1/3MnO3 thin films grown with pulsed laser deposition. The experiments are performed in the 100 mirror plane. The experimental results are related to GGA U calculations through simulations of photoemission spectra, which take into account the final state broadening in surface-perpendicu...
متن کاملHalf-metallic ferromagnets: From band structure to many-body effects
A review of new developments in theoretical and experimental electronic structure investigations of half-metallic ferromagnets (HMF) is presented. Being semiconductors for one spin projection and metals for another ones, these substances are promising magnetic materials for applications in spintronics (i.e., spin-dependent electronics). Classification of HMF by the peculiarities of their electr...
متن کاملHalf-metallic ferromagnetism of MnBi in zincblende phase
The full-potential augmented plane wave plus local orbitals method within density-functional theory is used to predict that MnBi in the zincblende phase is a true half-metallic ferromagnet with a magnetic moment of 4:000mB per formula. This phase of MnBi is found to be robust against volume changes from 12% to þ30% and remains qualitatively the same under various exchange-correlation approximat...
