Popis:	The magnetic properties of Gd/Ho superlattices have been investigated using neutron-diffraction techniques. Between and , the magnetic moments in each Gd block order ferromagnetically in the basal plane with the moments in adjacent Gd blocks antiferromagnetically aligned. At temperatures below , the Ho moments order in a basal-plane helix, while the Gd moments remain ferromagnetically aligned in the basal plane with an alignment between adjacent Gd blocks that is dependent on temperature and the Ho-block thickness. The coherence lengths of the magnetic structures in the growth direction range from 350 A to 800 A. Comparisons are made with the results from previous studies of heavy rare-earth superlattices.
