Preparation of 3d nanoparticles by magnetron sputtering and deposition on a W(110) surface — •Marek Wilhelm, Hendrik Bettermann, and Mathias Getzlaff — Institute of Applied Physics, University of Duesseldorf
The scientific research of nanoparticles is a broad interdisciplinary area of research, development and industrial activity. Our work is focused on the electronic and the magnetic behaviour which depends on the size and structure of particles. This contribution has an emphasis on FeNi alloy nanoparticles deposited on a W(110) surface. The particles are generated by a magnetron sputter source and subsequently mass selected in a quadrupole. Magnetron sputtering is possible due to thin sputter targets. Scanning Tunneling Microscopy (STM) is the main method to study these objects. The whole measurement system works in an ultra high vacuum environment in the order of 5·10−10 mbar. We will report on our first results of this setup concerning size and structual properties of FeNi nanoparticles with diameters up to 5 nm.
