摘要：

A refinement of the neutron diffraction pattern of YbCu5-xAlx compounds shows that the Al atoms are built in preferentially on the (3g) sites of the hexagonal CaCu, crystal structure. Long range antiferromagnetic order, caused by this substitution, appears well below 2 K in YbCu3Al2 with ordered moments in the c-direction of about mu(Yb) = (2.10 +/- 0.05)mu(B).
