Spin dependent anisotropy in the momentum density of ferromagnetic nickel metal

Directional spin dependent Compton profiles of ferromagnetic nickel metal have been measured with 55 keV circularly polarised synchrotron radiation and the results have been compared with an APW calculation of the electron momentum density. At low momenta where the negatively polarised 4s-p band reduces the spin dependent momentum density, the model predicts accurately the contribution to the (100) lineshape but significantly underestimates the (111) profile.
