The traditional Landau theory of second-order phase transitions is used to analyze the behavior of the magnetothermal properties of simple ferromagnets as functions of the temperature, the magnetic field, and the thermodynamic theory parameters that have not been thermodynamically interpreted earlier. A number of generally accepted concepts of the magnetocaloric effect (MCE) are shown to require refinement. The thermodynamic consideration is comprehensively illustrated by model calculations performed on real temperature and magnetic-field scales, and the calculation results are compared with the experimental data obtained for ferromagnetic gadolinium. Thermodynamic conditions required for reaching the maximum MCE in simple ferromagnets have been formulated.
