1. Magnetocaloric and barocaloric effects in Mn[As(1-x) Sb(x)] e La[Fe(x) Si(1-x)]13 / Efeitos magnetocalórico e barocalórico em Mn[As(1-x) Sb(x)] e La[Fe(x) Si(1-x)]13
Recent experimental data revealed that the compounds La[Fe(x)Si(1-x)]13 and Mn[As(1-x)Sb(x)], present great values for the isothermal entropy change and the adiabatic temperature change. They also showed that the magnetocaloric effect in these compounds can be easily tuned through doping and external pressure. Therefore, such experimental data, which need a

2. Magnetic and barocaloric effect in physical systems with two energy levels / Efeitos magnetocalórico e barocalórico em sistemas físicos com dois níveis de energia
In this work we study the theoretical aspects of the magnetocaloric and barocaloric effect in simple physical systems with two and four energy levels. In order to do that, we used a Hamiltonian that consider local magnetic moments interacting among them and with an external magnetic field.We include in the Hamiltonian the magnetoelastic interaction, and an e
