Abstract
The effect of hydrogen on the magnetism in both cluster and bulk material o f ferromagnetic metal nickel was investigated using first-principles calcul ations. It is found that the interaction of H atoms with the host atoms dec reases the exchange interaction and suppresses magnetism. Thermodynamic ana lysis has also been made for the temperature and magnetization dependency o f hydrogen solubility near the Curie point in bulk nickel using the extende d higher order regular solution model.
