Abstract

Laser ablation deposition (LAD) is a very promising technique for the preparation of thin films and multilayers. Technical difficulties inherent in the method have been solved. In particular a velocity selector has been developed leading to almost complete elimination of the droplets ejected from the target. The magnetic properties of a series of model systems prepared by LAD have been studied. The anisotropy of 30ÅFe(110)/W(110)/Al 2O 3(112¯0) is discussed. Epitaxial bilayers of 5ÅGd(0001)/25ÅFe(110)/W(110) have been obtained; the Gd moments are antiparallel to the Fe moments. Thin films of Y 2Co 17(0001) have been successfully grown on W(110)/Al 2O 3(112¯0) and their magnetic properties have been characterized.
