Epitaxial thin-films of DyxPr1-x alloys have been studied using neutron dif
fraction and magnetization measurements. The crystal structure changes from
HCP to Sm type to DHCP as x decreases; each crystal phase has different ma
gnetic behaviour. Surprisingly, long-range order is suppressed in the DHCP
allays, a possible explanation is outlined. (C) 2000 Elsevier Science B.V.
