Specific Heat of a Ferromagnetic Substance Above the Curie Point

High-temperature expansions for the specific heat of the Ising model are compared for the triangular and f.c.c. lattices. It is concluded that the "tail" of the specific heat curve above the Curie point is much smaller for the f.c.c. lattice, but is steeper in the immediate neighborhood of the Curie point. For the Heisenberg model for the f.c.c. lattice the tail is larger but apparently much less steep.
