Abstract
Using high-resolution core-level photoelectron spectroscopy and modified Anderson impurity model calculations, we study the Mn 2p spectrum of manganese metal and resolve the current debate about its spectral shape. An unusual satellite feature, 1 eV from the main peak, is observed in the Mn 2p3/2 spectrum of a thick Mn layer grown on Al. It originates from intra-atomic multiplet effect related to Mn atoms with large local moment. The satellite decreases in intensity for thin Mn layers and for Al deposition on bulklike Mn because of enhanced Mn 3d hybridization with Al s,p bandlike states. The reason for the absence of a charge-transfer satellite is discussed.
