Profile of the U5fmagnetization inU∕Femultilayers

We have used the x-ray resonant magnetic reflectivity technique to obtain the profile of the induced uranium magnetic moment for selected $\mathrm{U}∕\mathrm{Fe}$ multilayer samples. This study extends the use of x-ray magnetic scattering for induced moment systems to the $5f$ actinide metals. The spatial dependence of the U magnetization shows that the predominant fraction of the polarization is present at the interfacial boundaries, decaying rapidly towards the center of the uranium layer, in good agreement with predictions.
