Soft X-ray resonant magnetic scattering from a Ni layer with modulated magnetic anisotropy
Structural and magnetic characterization of a magnetically modulated, but nominally chemically homogenous, 5 nm Ni layer in a Cu/Ni/Cu thin film system was performed using specular reflection and rocking scans in X-ray resonant magnetic scattering, probing the scattering vector components in the perpendicular and in-plane direction to the Ni wires, respectively. Using polarized soft X-rays at the Ni
L2,3 resonance energy the measured magnetic scattering intensity reveals the magnetic modulation of the Ni layer. The results demonstrate the large potential of this element-specific scattering technique to study such complex magnetic structures in artificially patterned samples.
