The chemical and magnetic structures of neodymium/praseodymium superlattices grown by molecular-beam epitaxy have been determined using x-ray and neutron-diffraction techniques. The x-ray measurements show that the superlattices have a dhcp structure

The molecular beam epitaxy growth techniques which have already successfully produced a range of heavy rare-earth superlattices have now been extended to produce superlattices of two light rare-earth elements, Nd Pr , as well as superlattices and all

Neutron diffraction studies of light rare-earth Nd/Pr superlattices show that there is a long-range ordered magnetic structure throughout the superlattice, and that both Nd and Pr moments are ordered.

The magnetic phase diagram of single crystal thin films of Ho/Er alloys has been determined by using neutron-scattering techniques. The results show an unusual penta-critical point at which the paramagnetic, basal-plane helix, tilted helix, cycloid a

The magnetic structures of a series of Ho/Er alloys have been determined by neutron-diffraction techniques. The alloys were prepared as thin films (10000 Angstrom thick) by molecular beam epitaxy, and are single crystals with a mosaic spread of about

The structural and the magnetic ordering in thin-film ${\mathrm{Ho}}_{x}{\mathrm{Pr}}_{1\ensuremath{-}x}$ alloys have been studied using neutron- and x-ray-diffraction techniques. As the concentration of Ho decreases the alloys adopt hexagonal-close-
