摘要：

Magnetic dichroism has been observed in the angular distributions of Fe 2p photoemission spectra excited from Fe(001) by unpolarized 1.25-keV x rays. The dichroism varies strongly around each low-index forward-scattering direction in the crystal, exhibiting an antisymmetry with emission direction and binding energy that is centred on each forward scattering peak. Photoelectron diffraction theory provides a quantitative explanation for these unpolarized dichroism effects, which should also be generally useful in surface magnetism studies.
