Spin density in ferromagnetic nickel: a magnetic Compton scattering study

Abstract: The magnetic Compton profiles (MCPs) measured in the [100], [110], [111] and [112] directions in single-crystal nickel with an incident photon beam of energy 224 keV are presented and discussed. The momentum resolution achieved, of 0.43 atomic units, improves on previous studies by almost a factor of two, and facilitates the interpretation of the MCPs in terms of the underlying spin-dependent momentum densities. Calculations have been performed using the linear muffin-tin orbital method, within both the loca… Show more

“…The advent of high intensity, high energy and well-polarized synchrotron sources and the spectrometers with high resolution (∼ 0.12a.u.) have resulted in revival of interest in this area [13][14][15] . On the theoretical side, high performance computing facilities have made it possible to perform calculations on a fine p-mesh with a better convergence criteria for the total energy and charge density self-consistency.…”

“…In the range of the studied values of U qualitative and quantitative differences are seen in the Compton profiles depending weather the LSDA is supplemented with static or dynamical many-body corrections. An important message is that relativistic effects and electronic correlations may have a non-trivial interplay and dynamical correlations determine larger relativistic corrections in the electronic [71,72]. The experimental momentum resolution is 0.43 a.u., which was also used as Gaussian broadening parameter for the calculated MCP spectra.…”
