Majority- and minority-spin-band directional Compton profiles in iron

Abstract
Directional magnetic Compton profiles in BCC iron have been measured with circularly polarised 60 keV synchrotron radiation. Further measurements on iron, which are of improved statistical quality, enable majority and minority directional difference profiles to be separated and a more specific test of band theory to be made. The results are generally in good agreement with APW calculations, except in low-momentum regions, where there are significant discrepancies.
