Electronic structure of a stabilized bulk-like α-Mn thick film on W(110) — •Elena Voloshina¹, Yuriy Dedkov², and Manuel Richter³ — ¹Institut für Chemie und Biochemie - Physikalische und Theoretische Chemie, Freie Universität Berlin, Germany — ²Fritz-Haber Institut, Berlin, Germany — ³IFW Dresden, P.

We report on the successful stabilization of thick bulk-like α-Mn films with (110) orientation on W(110) substrate. The observed (3× 3) patterns are consistent with the presented growth model. Angle-resolved photoemission spectra show weak dispersions of the valence band electronic states. These PE data are analyzed on the basis of DFT calculations for non-magnetic bcc α-Mn. The observed weak dispersions are caused by the large number of inequivalent Mn atoms of the α-Mn structure.
