Fermi surface of an important nano-sized metastable phase: Al$_3$Li

Autor: Laverock, J., Dugdale, S. B., Alam, M. A., Roussenova, M. V., Wensley, J., Kwiatkowska, J., Shiotani, N.

Publikováno v: Phys. Rev. Lett. 105, 236401 (2010)

Nanoscale particles embedded in a metallic matrix are of considerable interest as a route towards identifying and tailoring material properties. We present a detailed investigation of the electronic structure, and in particular the Fermi surface, of

Report

Anomalous electronic correlations in ground state momentum density of Al$_{97}$Li$_3$

Autor: Kwiatkowska, J., Barbiellini, B., Kaprzyk, S., Bansil, A., Kawata, H., Shiotani, N.

Publikováno v: Phys. Rev. Lett. 96, 186403 (2006)

We report high resolution Compton scattering measurements on an Al$_{97}$Li$_3$ disordered alloy single crystal for momentum transfer along the [100], [110] and [111] symmetry directions. The results are interpreted via corresponding KKR-CPA (Korring

A Novel 2D Folding Technique for Enhancing Fermi Surface Signatures in the Momentum Density: Application to Compton Scattering Data from an Al-3at%Li Disordered Alloy

Autor: Matsumoto, I., Kwiatkowska, J., Maniawski, F., Itou, M., Kawata, H., Shiotani, N., Kaprzyk, S., Mijnarends, P. E., Barbiellini, B., Bansil, A.

Publikováno v: Phys. Rev. B 64, 045121 (2001)

We present a novel technique for enhancing Fermi surface (FS) signatures in the 2D distribution obtained after the 3D momentum density in a crystal is projected along a specific direction in momentum space. These results are useful for investigating

Report

A High-Resolution Compton Scattering Study of the Electron Momentum Density in Al

Autor: Ohata, T., Itou, M., Matsumoto, I., Sakurai, Y., Kawata, H., Shiotani, N., Kaprzyk, S., Mijnarends, P. E., Bansil, A.

We report high-resolution Compton profiles (CP's) of Al along the three principal symmetry directions at a photon energy of 59.38 keV, together with corresponding highly accurate theoretical profiles obtained within the local-density approximation (L
