Abstract
A simple model describing antiferromagnetic-type spin fluctuations is developed to discuss the resistivity and magnetic susceptibility of actinide systems at high temperatures. It is found that the resistivity goes through a maximum and saturates at high temperatures, independently of the nature of the spin fluctuations. On the other hand, the magnetic susceptibility may be roughly temperature independent in the case of antiferromagnetic spin fluctuations, while it decreases rapidly in the ferromagnetic case. The first case applies to Np and Pu metals and some compounds, while the second case applies to compounds such as UAl 2 , PuAl 2 , NpRh 3 , and USn 3 .
