Actinide compounds with 5f electrons have been attracting much attention<br />
because of their interesting magnetic and electronic properties such as heavy<br />
fermion state, unconventional superconductivity, co-existence of the<br />
superconductivity and magnetism. Recently, we have reported a phenomenological<br />
analysis on 80 actinide ferromagnets with the spin fluctuation theory<br />
originally developed to explain the ferromagnetic properties of itinerant<br />
ferromagnets in the 3d transition metals and their intermetallics (N. Tateiwa<br />
et al., Phys. Rev. B 96, 035125 (2017)). Our study suggests the itinerancy of<br />
the $5f$ electrons in most of the actinide ferromagnets and the applicability<br />
of the spin fluctuation theory to actinide 5f system. In this paper, we present<br />
a new analysis for the spin fluctuation parameter obtained with a different<br />
theoretical formula not used in the reference. We also discuss the results of<br />
the analysis from different points of views.
