To make a theoretical investigation of the effect of magnetic transition on hydrogen dissolution in magnetic metals or alloys, the higher-order regular solution model was extended to include the exchange interaction between the collinear magnetic moments of metallic atoms and the chemical interaction between nonmetallic atoms and metallic atoms. Using the extended model, the dependency of hydrogen solubility on temperature in ferromagnetic metals Fe, Co, and Ni was studied. It was found that magnetization does not favor the dissolution of hydrogen.
