Description
Summary: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 30 A Fe(110) /W(110)/Al sub 2 O sub 3 (11-20) is discussed. Epitaxial bilayers of 5 A Gd(0001)/25 A Fe(110)/W(110) have been obtained; the gadolinium moments are antiparallel to the iron moments. Thin films of Y sub 2 Co sub 17 (0001) have been successfully grown on W(110)/Al sub 2 O sub 3 (11-20) and their magnetic properties have been characterized.
