The magnetic entropy change, Δ SM, of Co (S1-x Sex) 2 has been studied for 0≤x≤0.11. Compounds with 0.03≤x≤0.11 undergo a first-order magnetic transition and exhibit itinerant electron metamagnetism (IEM) just above the Curie temperature. We observed that the peak value of Δ SM shows a maximum at around x=0.07. The results are compared with the theoretically calculated results based on the spin fluctuation theory of IEM reported by Yamada and Goto. It is found that the experimental results are well described by the theoretical calculations. The origin of the peak of Δ SM is discussed from the thermodynamical point of view.
