Ti12xScxN alloys were used to investigate the effects of carrier density and the density of states ~DOS! at the Fermi level E f on vibrational modes, phonon anomalies, and superconducting transition temperatures Tc . Single-crystal Ti12xScxN layers, 2000 Å thick, with compositions spanning the entire alloy range (0<x <1), were grown on MgO~001! by ultrahigh vacuum reactive magnetron sputter dep...

Using scanning and transmission electron microscopy, the analysis of structure, phase elemental composition contact zone system coating (high-entropy FeCrCoNiMn alloy)-substrate (5083 alloy) after electron-beam processing was performed. The formation a multiphase, multielement submicro- nanocrystalline structure has been established. high-speed cellular crystallization in layers adjacent to sub...

Complex, end-to-end network services are set up via the configuration method: each component has a finite number of configuration parameters each of which is set to a definite value. End-to-end network service requirements can be on connectivity, security, performance and faulttolerance. However, there is a large conceptual gap between end-to-end requirements and detailed component configuratio...

The transport properties of two types spin valves are analyzed, in which the Heusler alloy Co 2 Cr 1-x Fe x Al y was used as one ferromagnetic layers F1/F2/S structures. layer used: 1) a weak ferromagnet, case F2 layer; 2) halfmetal, F1 layer. In first case, large classical effect superconducting valve Delta T c obtained, facilitated by significant triplet contribution to trip . second gigantic...
