The performance of spintronics depends on the spin polarization of the current. In this study half-metallic Co-based full-Heusler alloys and a spin filtering device (SFD) using a ferromagnetic barrier have been investigated as highly spin-polarized c

The structures of epitaxial ultrathin Co2FeAl/MgO(001) heterostructures relating to the interface-induced perpendicular magnetic anisotropy (PMA) were investigated using scanning transmission electron microscopy, energy dispersive x-ray spectroscopy,

We have investigated the structural, magnetic and barrier properties for Co-ferrite thin films, which have been formed by plasma oxidization of the surface of Co33Fe67(CoFe2) underlayer deposited on MgO(001) single crystal substrates. XRD patterns an

Heusler alloys are theoretically predicted to become half-metals at room temperature (RT). The advantages of using these alloys are good lattice matching with III–V semiconductors, high Curie temperature above RT and intermetallic controllability f

Recently half-metallic full-Heusler alloy films have attracted significant interests for spintronics devices. As these alloys have been known to have a high spin polarization, very large TMR ratio is expected in magnetic tunnel junctions. Among these

In this paper, we studied the influence of deposition angle during the aerosol deposition (AD) method. The deposition angle was changed from 0° to 45°. The density of films did not change, but the surface roughness was improved by the inclination o

We have investigated the structural and magnetic properties for Co2(Cr1� xFex)Al (x ¼ 0:4, 0.6 and 1.0) full-Heusler alloy films deposited on MgO(001), MgO(011) and sapphire (a-plane) substrates by magnetron sputtering. Substrate temperatures were

Co2V0.67Fe0.33Al full-Heulser alloy films were fabricated on an MgO (100) single crystalline substrate by using two different heat treatments: substrate heating and post-annealing. Ultra-high-vacuum dc magnetron sputtering was used to prepare the sam
