Preliminary results are reported for a magnetic study of the Sm-Gd alloy system. For Gd-rich alloys, the results show a ferromagnetic transition with Curie temperature decreasing to approximately 255 K for 30% Sm. For the Sm-rich end of the alloy range, the Sm-type antiferromagnetic transitions are seen. The ferromagnetic influence of Gd clearly exists down to Gd concentrations of 20%, where a ferromagnetic-like transition is seen with a Curie temperature of 180 K. In one sample of 60% Sm--40% Gd, we have seen evidence of different magnetic regions, one of which is a Gd ferromagnet with a {ital T}{sub {ital c}} of approximately 290 K.
