The specific heat and magnetocaloric effect of the LaFe11.2-хMnxCo0.7Si1.1 intermetallic compounds (x = 0.1, 0.2, 0.3) were measured in the temperature range 80–300 K and in magnetic fields up to 8 T. The magnetocaloric effect (MCE) was estimated using two methods: direct method in cyclic magnetic fields, as well as an indirect method from heat capacity data. It was shown that an increase in the concentration of Mn atoms leads to a shift in the Curie temperature of the TC toward lower temperatures, while the FM value changes slightly.
