Role of Hydrogen Atoms in Palladium

抄録

The Hall coefficient and magnetic susceptibility of the hydrides of palladium silver alloys are measured as a function of hydrogen content in order to clarify the role of hydrogen in palladium. From the relation between the magnetic property and the hydrogen content, it is concluded that a valence electron of hydrogen plays a similar role in the hydride to that of a valence electron of silver atom in palladium-silver alloys. In diamagnetic region, that is, in higher content region of β-phase, the Hall coefficient considerably decreases with increasing hydrogen content, indicating that a valence electron of a hydrogen atom takes a part in conduction.
