Abstract
Results are reported for the magnetic transitions in quasi-binary CeFe2 alloys with substitutions of Al or Mn on the Fe sites and substitutions of Y or U on the Ce sites. The transitions have been studied by magnetic susceptibility and electrical resistance measurements, and comparisons are made with previous work involving alloying with a number of other transition metals, especially Co and Ru. The role of 4f-3d hybridisation indicated by theory is emphasised in the discussion, as are the variety of magnetic phase diagrams possible and the possible influence of changes in the effective valency of cerium.Keywords
