Abstract

The domain structure of relatively thick RF-sputtered CoCr (81:19 at %) layers with a columnar morphology in the range of thickness 1-5 mm was investigated using a polarised neutron beam. On the basis of the results a model of straight domains running through the entire film thickness has to be rejected. Arguments are given for a serpentine-like domain structure with a domain width about the same as the column diameter (0.1-0.3 mm), resulting in a 'chain of columns' model.
