Effect of O contamination on magnetic properties of ultrathin Mn films grown on (001) Fe

Magnetic ordering in Fe/Mn superlattices

“…The observed magnetic structure confounds all of the theoretical predictions for Fe/Mn superlattices [6] and previous XMCD measurements of Mn overlayers grown on Fe [7], which indicate that the Mn should form a fully uncompensated exchange-biasing layer. The observed Mn ordering may be due to the frustration resulting from terracing at the interfaces or, alternatively, the tetragonal distortion arising from epitaxy.…”

X-ray magnetic circular dichroism analysis of thermally annealed Co53Mn25B10Si12 amorphous alloy

“…The clearly resolved doublet structure of 2p 1/2 peak suggests that hybridization between Mn and its neighboring atoms was substantially reduced compared to the metallic state [13]. The reduced hybridization allowed the final state effects, which are not normally observed in metallic Mn, to become visible [14,15]. L 2,3 absorption spectrum for Ni also exhibits the multiplet structure in spite of being in metallic state, similar to Fig.…”

Spin polarization at the NiMnSb/MgO(100) interface

“…The Mn monolayer was grown on a thick (0 0 1) Fe buffer layer epitaxially grown on a (0 0 1) MgO substrate. The Mn atomic moments are thus ferromagnetically coupled with Fe, and an average magnetic moment is observed by XMCD at the L2,3 Mn edge [29]. Moreover, the shape of this Mn L edge is typical of a metallic state.…”
