We analyze the influence of the surface-induced anisotropy of magnetic-impurity spins on the magnetization of thin polycrystalline films, consisting of weakly-coupled grains of homogeneous dilute magnetic alloys. The calculated magnetization depth profiles across such AuFe films appear to be very sensitive to the grain shape. Based on these calculations, we theoretically study the reflection of polarized neutrons by AuFe films with different microstructure and show that polarized-neutron reflectivity measurements can provide a direct probe of the surface-induced magnetic anisotropy of the impurity spins in films of dilute magnetic alloys. |
