Extreme Fermi surface smearing in a maximally disordered concentrated solid solution
Hannah C. Robarts, Thomas E. Millichamp, Daniel A. Lagos +13
We show that the Fermi surface can survive the presence of extreme compositional disorder in the equiatomic alloy NiFeCoCr. Our high-resolution…
Fermiology via the electron momentum distribution
G. Kontrym-Sznajd
Investigations of the Fermi surface via the electron momentum distribution reconstructed from either angular correlation of annihilation radiation (or Compton scattering) experimen…
On the reliability of linear band structure methods
G. Kontrym-Sznajd, M. Samsel-Czekala, G. E. Grechnev +1
We discuss an efficiency of various band structure algorithms in determining the Fermi surface (FS) of the paramagnetic ErGa3. The linear muffin-tin orbital (LMTO) in the atomic sp…
Observation of a strongly nested Fermi surface in the shape-memory alloy Ni[0.62]Al[0.38]
S. B. Dugdale, R. J. Watts, J. Laverock +7
The Fermi surface topology of the shape-memory alloy Ni[0.62]Al[0.38] has been determined using Compton scattering. A large area of this Fermi surface can be made to nest with othe…
Many-body effects observed in the positron annihilation experiment
G. Kontrym-Sznajd, H. Sormann
This paper is devoted to study many-body effects in the positron annihilation experiment, both electron-positron (e-p) and electron-electron (e-e) correlations. Various theories of…
Different ways of dealing with Compton scattering and positron annihilation experimental data
G. Kontrym-Sznajd, M. Samsel-Czekala
Different ways of dealing with one-dimensional (1D) spectra, measured e.g. in the Compton scattering or angular correlation of positron annihilation radiation (ACAR) experiments ar…
