Depth Profile of the Phase Transition of the FeRh Alloy in FeRh/BaTiO3
Attila Lengyel, Gábor Bazsó, Aleksandr I. Chumakov +9
We report on the depth dependence and technological limits of the phase transition of the iron rhodium alloy as function of temperature, external magnetic and electric fields in th…
Lattice dynamics of endotaxial silicide nanowires
J. Kalt, M. Sternik, B. Krause +17
Self-organized silicide nanowires are considered as main building blocks of future nanoelectronics and have been intensively investigated. In nanostructures, the lattice vibrationa…
Lattice dynamics and polarization-dependent phonon damping in -phase FeSi nanoislands
J. Kalt, M. Sternik, B. Krause +16
We determined the lattice dynamics of metastable, surface-stabilized -phase FeSi nanoislands epitaxially grown on the Si(111) surface with average heights and widths ranging…
Phonons in ultrathin oxide films - 2D to 3D transition in FeO on Pt(111)
N. Spiridis, M. Zając, P. Piekarz +10
The structural and magnetic properties of ultrathin FeO(111) films on Pt(111) with thicknesses from 1 to 16 monolayers (ML) were studied using the nuclear inelastic scattering (NIS…
Lattice dynamics of α-cristobalite and the Boson peak in silica glass
Björn Wehinger, Alexeï Bosak, Keith Refson +3
The lattice dynamics of the silica polymorph α-cristobalite has been investigated by a combination of diffuse and inelastic x-ray scattering and ab initio lattice dynamics calculat…
Lattice dynamics of coesite
Björn Wehinger, Alexeï Bosak, Aleksandr Chumakov +7
The lattice dynamics of coesite has been studied by a combination of diffuse x-ray scattering, inelastic x-ray scattering and an ab initio lattice dynamics calculation. The combine…
Importance of correlation effects in hcp iron revealed by a pressure-induced electronic topological transition
K. Glazyrin, L. V. Pourovskii, L. Dubrovinsky +17
We discover that hcp phases of Fe and Fe0.9Ni0.1 undergo an electronic topological transition at pressures of about 40 GPa. This topological change of the Fermi surface manifests i…
Theory of Incoherent Nuclear Inelastic Resonant Scattering of Synchrotron Radiation
V. G. Kohn, A. I. Chumakov
The theory of incoherent nuclear resonant scattering of synchrotron radiation accompanied by absorption or emission of phonons in a crystal lattice is developed. The theory is base…
