Abstract

Specular and off-specular polarized neutron reflectometry of strong biquadratic coupling in a Cu<sub>0.94</sub>Mn<sub>0.06</sub>/Co multilayer is presented. Detailed analysis of the reflectivity via the distorted-wave Born approximation reveals a formation of on average 〈±30<sup>∘</sup>〉 canted lateral magnetic domains. Domains with mean width of 0.43 μm extend throughout the multilayer structure and magnetization alternates in the sign of the canting with subsequent layers. Temperature and field dependence of the magnetic structure are evaluated and included in the magnetic model, which is used to deduce bilinear and biquadratic interlayer exchange coupling energies.
