Mn L2,3 x-ray absorption spectra of a diluted Mn–Ge alloy

An ion implanted Mn–Ge(100) alloy has been fabricated with a 30nm subsurface layer of disorderly diluted Mn atoms, which settle all in substitutional lattice sites after 400°C annealing in vacuum. The Mn L2,3 x-ray absorption spectroscopy of the disordered Mn implanted alloy is featureless, while the one taken on the alloy with complete substitutional Mn dilution shows a Mn2+ multiplet structure.
