(Ga,Mn)As and (Ga,Mn)N are so called diluted magnetic semiconductors, i.e. semiconductor based materials made ferromagnetic by inclusion of a magnetic element—in this case Mn. This type of materials bridge over the incompatibilities in metal–semiconductor interfaces in electronics components and have an enormous potential for future spintronics applications, where both charge and spin degrees o...

The electronic, magnetic, and optical behaviors of metals (M = Ag, Al, Au, Bi, Ca, Co, Cr, Cu, Fe, Ga, K, Li, Mn, Na, Ni) adsorbed on the SiC monolayer have been calculated based density functional theory (DFT). binding energy results show that all M-adsorbed systems are stable. All magnetic with moments 1.00 μB (Ag), (Al), (Au), 1.01 (Bi), 1.95 (Ca), (Co), 4.26 (Cr), (Cu), 2.00 (Fe), (Ga), 0.9...

For multistage displacive structural transitions we present a general framework that accounts for various intermediate modulated phases, elastic constant, phonon, and related thermodynamic anomalies. Based on the presence or absence of modulated phases we classify these transformations in four categories and apply this approach to four different representative materials Ni-Mn-Ga ~or a-U), NiTi~...

Abstract The influence of CuO/ZrO 2 /ZnO (Cu/Zr/Zn) catalyst modification with Mn, Ni, Ga on the physicochemical properties and activity toward hydrogen production in steam reforming ethanol (SRE) reaction has been evaluated. increase yield lowest selectivity to acetaldehyde were observed upon Cu/Zr/Zn Mn Ga. characterisation spent catalysts revealed changes phase compositions reducibility. In ...

First-principles total-energy electronic structure calculations based on the full-potential linear-muffin-tinorbital method have been used to study the electronic and mechanical properties of the L12-type ordered nickel-based intermetallics Ni3X ~X5Mn, Al, Ga, Si, Ge!. The calculated values for the equilibrium volume and elastic properties are generally in good agreement with experiments. The l...
