Thin films of (CoCrCuFeNi) N x were deposited by direct current reactive magnetron sputtering. Two different targets were used. Thin films deposited from a solid near-equimolar target showed a Cu excess with segregation of Cu in the film resulting in

Elastic properties of as-cast TiHfZrTaNb high entropy alloy were investigated by ultrasound measurements, yielding G=C44=28 GPa and C11=172 GPa effective isotropic elastic constants, allowing computation of the Young’s modulus E, the bulk modulus B

The structural and elastic properties of the ternary silicides ScTSi (T═Co, Ni, Cu, Ru, Rh, Pd, Ir, Pt) and of the equiatomic intermetallic YTX (T═Ni, Ir; X═Si, Ge, Sn, Pb) are studied using the density-functional theory considering the orthorh

Brillouin light scattering (BLS) was conducted on melt-grown ZnO bulk crystals and ZnO thin films grown by pulsed laser deposition. The bulk ZnO crystals presented both longitudinal and transverse bulk acoustic waves. Theoretical calculations agreed

International audience; We comparatively study the elastic properties of the two existing polytypes of tantalum, α-Ta (ground state bcc structure) and β-Ta (metastable tetragonal structure), using density functional theory (DFT) calculations and th

We report the investigations of spin wave modes of arrays of Ni and Co nanorods using Brillouin light scattering. We have revealed the significant influence of spin wave modes along the nanorod axis in contrast to infinite magnetic nanowires. Unusual

Elastic properties of Mo1 − xSix alloy films with 0 ≤ x ≤ 1 have been investigated by the Brillouin light scattering technique thanks to the analysis of the surface acoustic waves in the film on substrate: the so-called Rayleigh surface wave an

The lattice dynamics of the ternary ZnSe 1-x Te x alloy have been studied using first-principles calculations. These are done using the density-functional perturbation theory (DFPT) within the local density approximation (LDA) and employing the virtu

We report on the first measurements of the physico-mechanical properties of the raffia textilis fiber. This fiber is the epidermis of the leaflet and is used to fabricate many ethnographical items. Scanning electron microscopy reveals a layered struc

High-pressure effects on the lattice dynamics and dielectric properties of the BN, BP, BAs, BSb and BBi alloys have been carried out using the density-functional perturbation theory within the local density approximation. We study the variation of th
