The behaviour of the Curie points at P ⪅ 15 kbar and of the magnetization at atmospheric pressure and 4.2 ≦ T ⪅ 100 K is investigated for hydrogen solid solutions on the base of disordered f.c.c. NiMn alloys containing 10, 20, and 30 at% Mn. The samples for the magnetization measurements are hydrogenated at P ≦ 70 kbar. It is shown that the observed effects may be explained within the framework of the band theory of magnetism considering hydrogen as a donor of a fractional quantity of electrons.
