Abstract
Amorphous Sm1-x cox -films with uniaxial in-plane anisotropy with various Co-concentrations 
and various film thicknesses d ( 
) have been prepared by flash-evaporation of SmCo-alloy powders. The saturation magnetization decreases linearly with x in the whole concentration range, whereas the coercive field increases linearly with x down to 
and then decreases. Drastic changes in all magnetic properties occur when at a given chemical composition the film thickness is reduced below 
nm. Head-on domains are separated by zig-zag walls whose amplitudes are analyzed as a function of the material parameters.
