Abstract: The effect of ordering on the thermal characteristics of the magnetic and martensite transitions in the Fe–Pt alloy with a composition close to stoichiometric Fe$_3$Pt composition is analyzed. It is found that a transition to a partly ordered state reduces the specific heat variation and thermal effect of the material due to the magnetic transition.
