Bulk susceptibility and high-resolution neutron-diffraction measurements have been performed on single crystals of Eu/sub x/Sr/sub 1-x/S for x = 0.52 and 0.54 near the ferromagnet (FM) - spin glass (SG) crossover. A reentrant phase is established, which is induced by random-field effects. As the temperature is reduced the FM correlation length xi passes through a resolution-limited maximum where a frustrated FM phase is observed. In the SG at lower temperature xi decreases again and a coexisting FM component can be excluded. 6 figures.
