Abstract:
The talk gives an overview about x-ray diffraction experiments that might elucidate the connection between strain and magnetic properties of Co/Pd multilayers. Samples grown under different process conditions have been examined with X-ray reflectivity, rocking curve measurements and strain scans. It turns out that the Ar pressure during sputter deposition is very much correlated with the biaxial stress in the samples. Furthermore, ion beam patterning of the films after growth releases most of that stress built-up.
