The Zeeman splitting was measured for neutrons specularly reflected from a magnetic layer in a particular geometry. The neutron spins were quantized along an external magnetic field H, and the reflecting layer was magnetized in a different direction,

We show that the chemical depth profile of a film of unknown structure can be retrieved unambiguously from neutron reflection data by adding to the system a known magnetic layer. Three independent reflectivities are obtained by taking measurements wi

The spin structure of antiferromagnetic Fe/Cr multilayers has been investigated by polarized neutron reflectivity. Measurements were taken on freshly sputtered films as well as films annealed at different temperatures. For annealing temperatures up t

Grazing incidence neutrons are not only reflected and refracted from imperfect layers, but also partially scattered by lateral dishomogeneities. In general, scattering may take place both in the reflection plane (“forward scattering”) and out of

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 di

Polarized neutron reflection was used to determine the magnetic structure of two different antiferromagnetically coupled multilayer systems, Fe/Gd and Fe/Cr. In Fe/Gd, the Fe and Gd moments are coupled antiparallel at the interface. At low temperatur

At the Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory, pulses of protons accelerated in a synchrotron produce pulses of fast neutrons via the spallation process in an enriched uranium target. After moderation, the resulting pulse

Modest magnetic field gradients in the region of a reflecting sample surface (either magnetic or nonmagnetic) are sufficient to significantly perturb neutron reflectivity. Polarized neutron experiments on a 850 A-thick film of deuterated polystyrene
