Soft X-ray resonant magnetic scattering from a Ni layer with modulated magnetic anisotropy

[scattered intensity plot]2D plot of the photon energy- and scattering vector qx-dependence of the scattered intensity measured by rocking scans with 2Θ = 10º across the Ni L2,3 resonance of the magnetically modulated Cu/Ni/Cu.
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.
