Fresnel reflection of polarized neutrons was used to measure the dependence of magnetic induction B in materials as a function of depth from the surface. The penetration depth of a magnetic field is superconductors was investigated, as well as the remnant superconducting surface sheath when the applied field exceeded the critical value (H/sub c2/ < H < H/sub c3/ in type II superconductors). In addition ferromagnets in bulk and in thin layers were examined. The prototype instrument with which the measurements were made was described. 19 refs., 5 figs. (WRF)
