Electrodeposition of Fe/Au(111) ultrathin layers with perpendicular magnetic anisotropy

摘要

The magnetic state of electrodeposited iron on An(111) substrates is investigated during the electrodeposition process by means of in situ alternating gradient force magnetometer (AGFM) and in situ perpendicular magneto-optic Kerr effect measurements (PMOKE). A perpendicular magnetic anisotropy (PMA) is observed for a thickness below 2 monolayers (ML). In situ STM observations of the initial stages of iron growth and ex situ EXAFS are used to correlate the structure of films to their magnetic properties. (C) 2004 Elsevier B.V. All rights reserved.
