Abstract : object of this work is the study of structural and magnetic properties ofSm-Co based thin films. One important aim is to obtain large energy-product values,the primary requirement in the permanent magnet industry.The materials are prepared by sputter deposition and an anneal at elevatedtemperature is required to crystallize the film and form the hard magnetic phases. Nb isused as a buffer layer between the Si substrate and the Sm-Co film due to its mechanicalhardness and lack of chemical reactivity.The <<classical>> composition SmCo5 is prepared first in nanocrystalline form.High coercivities (up to 37 kOe) are obtained along with rather modest values for energyproduct (- 5 MG.Oe)....,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
