Local-spin-selective x-ray absorption and x-ray magnetic circular dichroism of MnP

Abstract The local-spin-selective X-ray absorption spectrum and the magnetic circular dichroism (MCD) spectrum are measured at the manganese K edge of MnP. A comparison of the two techniques makes it possible to determine the energy dependence of the Fano factor. It is found that the Fano factor is −4% at the edge while it decreases to values lower than 1% at all energies more than 7 eV above the edge.
