Abstract
The influence of geometric isotopic effects on the Curie temperature o f hydrogen-containing crystals was considered. The experimental pressu re and concentration dependencies of the Curie temperature have been e xplained in a framework of the pseudo-spin Ising model, by taking into account the changes in geometry of hydrogen bonds under pressure and due to isotopic exchange.
