Abstract

We have measured the specular reflectivity of spin-polarized neutrons from two (111) superlattices, [Pd 80 Å∥Co 60 Å]×20/Pd 300 Å/Co 10 Å/GaAs and [Pd 53 Å∥Co 32 Å]×10/Pd 30 Å/Cu 354 Å/Si, grown by molecular-beam epitaxy. In a saturating field of 2300 Oe, we extract for the first superlattice a Co moment value of corresponding to 78% of the bulk Co moment. At temperatures ranging from 38 to 295 K, no excess magnetic moment from polarization of the Pd atoms is evident in the nominal Pd layer. Comparable reflectivity data from the second sample support these conclusions.
