Based on the model calculation, it has been shown that the effect of hydration of the ferromagnetic compounds La(Fe0.88Si0.12)(13)H (y) is quantitatively adequately described by the introduction of a negative pressure. The calculations have been performed for compounds with hydrogen concentrations y = 0, 0.5, 1.0, and 1.5. It has been found that these concentrations correspond to the pressures P = 0, -0.95, -1.85, and -2.80 GPa, respectively. The calculated Curie temperature, magnetization, characteristics of the magnetocaloric effect, and other properties are in satisfactory agreement with experiment.
