The Curie temperature, T C , of a ferromagnetic system with different spins and different type interactions is considered – spin ½ with Ising‐like interaction J I , spin 1 with Heisenberg‐like interaction J H , and Ising‐like interaction J IH between unlike spin pair. The T C vs. p (concentration of Ising‐like spin) curves are drawn under different J H / J I and J IH / J I for square and s.c. lattices. The condition of the convex behaviour of the curves is discussed.
