摘要
By substituting copper for part of the beryllium in the C-15 Laves phase, TiBe2, the phase is converted into an itinerant electron ferromagnet. The stable C-15 phase forms over the general composition range, TiBe2-xCux where 0 ≤ x <.50 and the lattice parameter expands from an ao=6.4532 Å for TiBe2 to an ao=6.554 Å for the composition TiBe1.5Cu.5. The Curie temperature increases with increasing copper content. Since none of the constituent elements have a local moment in their metallic state, this material joins the other two truly itinerant ferromagnets, Sc3In and ZrZn2. © 1979.
