摘要	The magnetic properties of Tb2Co17-xAlx compounds with 0 less than or equal to x less than or equal to 4 were studied by means of magnetic measurements. There is a strong decrease of the saturation moment and the Curie temperature with AI concentration. In a previous investigation, it was shown that increasing AI concentration in R(2)Co(17-x)AI(x) compounds leads to a sign reversal of the magnetocrystalline Co-sublattice anisotropy from easy-plane anisotropy for low AI concentration to easy-axis anisotropy for higher AI concentration. In the Tb(2)Co(17-x)AI(x) compounds, the competition between the planar Tb-and easy-axis Co-sublattice anisotropy does not lead to spin-reorientation transitions because the Tb-sublattice anisotropy dominates at all temperatures. The occurrence of spin reorientations in R(2)Co(17-x)AI(x) compounds is discussed in terms of a simple model description.
