摘要：

About 20 powder samples of the fcc diluted system NipMg1-pO (0.06 < p < 1) were prepared and their structural and magnetic properties were measured. The lattice constant a(p) fits the variation a(p) = 4.2115 - 0.0340 p. From the magnetic susceptibility versus temperature data, the Neel temperatures T(N) are determined. The variaton of t = T(N)(p)/T(N)(1) versus p is found to be similar to that in CopMg1-pO for p > 0.32 and it is found to fit the predicted values for a simple cubic Heisenberg antiferromagnet. A theoretical justification for this observation is advanced.
