Abstract: Ultrathin palladium metal films were grown on C(0 0 0 1). Their composition, electronic structure and magnetic behavior were studied by synchrotron based techniques (XPS and XAS), LEED and magnetic measurements. The Pd films were deposited in UHV conditions (pressure <5 × 10-10 mbar) with thicknesses ranging from 1-2 to 12 ML. Annealing was performed to segregate Pd and to generate a cluster structure, which could induce the system to acquire magnetic properties as has been predicted by theoretical studies. To clarify the existence or not of ferromagnetic behavior in these samples, magnetic measurements were performed using a SQUID Magnetometer. © 2006 Elsevier B.V. All rights reserved.
