Epitaxial (1{bar 1}02) Dy/Y rare earth superlattices and a thick (1{bar 1}02) Dy film, grown on sapphire with Y/Ta buffer layers, have been prepared by molecular beam epitaxy. Neutron diffraction and SQUID magnetization measurements on a single 200 nm thick (1{bar 1}02) Dy layer showed nearly bulk behavior. However, for the (1{bar 1}02) Dy/Y superlattices we found different magnetic behavior depending on the relative Dy to Y-layer thickness. The superlattices exhibit both ferromagnetic and helical phases, but with the N{acute e}el and Curie temperatures significantly different from bulk Dy. These results differ from previous findings in Dy/Y superlattices grown along [0001]. {copyright} {ital 1996 American Institute of Physics.}
