摘要：

Using the strength of the Gd-Gd interactions, deduced in different Gd-T intermetallics from the ordering temperature of GdNi2, the Gd-T exchange coupling parameter (A(GdT) of the R(m)T(n) (T = Fe or Co; m/n = 1/2; 1/3; 6/23; 1/5 and 2/17) and R(m)T(n)A(k) (A = metalloids and other metals; m/n/k = 1/4/1; 2/14/1; 1/11/1 and 1/10/2) systems has been evaluated from analysis of the Curie temperature. Going from T-poor to T-rich compounds, a tendency to decrease is found for both A(Gd-Co) and A(Gd-Fe); these variations are compared with those observed in the exchange parameters A(Co-Co) and A(Fe-Fe).
