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.

In this work, we have studied the magnetocaloric effect (MCE) of a paramagnetic salt under the view of the Tsallis thermostatistics formalism. In order to model the paramagnetic salt we have used the simple two-level model. Within this model, it is possible to realize the role of the Tsallis parameter q for all thermodynamics variables calculated here, i.e. the internal energy, the specific heat, the entropy, and the magnetocaloric potential. The main result presented in this work is the relation between the total heat related to the MCE and the q-parameter of the Tsallis theory. There is a threshold value of q where, above this value, the total heat change is constant for all q while below this value, there is a quick decreasing.
