Large tunneling anisotropic magnetoresistance mediated by surface statesMarie Hervé1, •Timofey Balashov1, Arthur Ernst2, and Wulf Wulfhekel11Physikalisches Institut, Karlsruhe Institute of Technology, Wolfgang-Gaede-Strasse 1, 76131 Karlsruhe, Germany — 2Institute for Theoretical Physics, Johannes Keppler University Linz, Altenberger Strasse 69, 4040 Linz, Austria

Tunneling anisotropic magnetoresistance (TAMR) is an effect originating from the spin-orbit coupling (SOC). It is related to changes in the density of state of a magnetic layer upon changes of the magnetization axis. It has been observed in a large variety of magnetic thin films. In this communication we report on a large TAMR effect (up to 30 %) observed in hcp Co using scanning tunneling microscopy. With the help of ab initio calculations the TAMR can be traced back to the spin-polarized occupied surface state of Co which experiences a strong spin-orbit interaction.
