Half-metallicity and Slater-Pauling behavior in the ferromagnetic Heusler alloys
Half-metallic ferromagnets represent a new class of materials which attracted a lot of attention due to their possible applications in spintronics (also known as magnetoelectronics) [1]. Adding the spin degree of freedom to the conventional electronic devices has several advantages like non-volatility, increased data processing speed, decreased electric power consumption and increased integrati...
متن کاملElectronic Structure of Half-metallic Magnets
We have analyzed the electronic structure of half-metallic magnets based on first principles electronic structure calculations of a series of semi-Heusler alloys. The characteristic feature of the electronic structure of semi-Heusler systems is a d-d gap in the density of states lying at/close to the Fermi level depending on the number of valence electrons. We have employed various indicators o...
متن کاملElectronic transport in ferromagnetic alloys and the Slater-Pauling curve
Experimental measurements of the residual resistivity x of the binary-alloy system Fe1−xCrx have shown anomalous concentration dependence which deviates significantly from Nordheim’s rule. In the low x 10% Cr concentration regime the resistivity has been found to increase linearly with x until 10% Cr where the resistivity reaches a plateau persisting to 20% Cr. In this paper we present ab initi...
متن کاملAb initio calculation of the effective on-site Coulomb interaction parameters for half-metallic magnets
Correlation effects play an important role in the electronic structure of half-metallic (HM) magnets. In particular, they give rise to nonquasiparticle states above (or below) the Fermi energy at finite temperatures that reduce the spin polarization and, as a consequence, the efficiency of spintronics devices. Employing the constrained random-phase approximation (cRPA) within the full-potential...
متن کاملHalf 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...
