✦ Synopsis

A review is given of the role of polarized neutron reflectivity (PNR) in measuring the magnetic profile close to the surface and in thin films of superconductors and magnetic materials. For type I and type II superconductors PNR provided a new and direct determination of the penetration depth. For very thin ferromagnetic films PNR was able to determine the absolute value of the magnetic moments. In magnetic superlattices, formed by the alternation of ferromagnetic layers and nonmagnetic spacers, PNR was used to confirm the basic magnetic structure as well as to determine the direction of the magnetic moments of the individual layers. In addition to reflectivity, forward magnetic scattering may very well extend the usefulness of PNR to the case of laterally dishomogeneous systems.

The depth profiles of the epitaxial Ni 80 Fe 20 (1 1 1)/Ru(0 0 0 1) multilayers were studied by polarized neutron reflectivity and X-ray reflectivity. At the Ru thickness that the anti-ferromagnetic coupling was found, the magnetic moments between two Ni 80 Fe 20 interlayers show a biquadratic coupl
