ABSTRACT
Studies of electron density distributions through the Compton effect exploit the Doppler shift that occurs because the target electron, bound in a potential, must be moving. This phenomenon was first exploited by DuMond and co-workers within a decade of Compton’s discovery, then largely forgotten for thirty years. After a patchy renaissance it has acquired a new potency with the availability of synchrotron radiation. In particular the ability to produce high fluxes of circularly polarized x-rays has led to studies of the spin density in ferromagnets. Magnetic Compton scattering experiments provide the only direct probe of the bulk ground state spin density distribution in ferro/ferri-magnetic materials. They are often sufficiently characteristic of the element that site-specific contributions can be extracted and conduction electron polarization studied; such work is the focus of this paper. © 2000 American Institute of Physics.
