摘要：

The cerium intermetallic compounds CeRu//2 and Ce//2Fe//1//4B both readily absorb hydrogen at normal conditions of temperature and pressure. The two systems exhibit fundamental changes in their physical properties corresponding to the transformation from non-magnetic alpha -type cerium to magnetic gamma -type cerium with a localized magnetic moment. Magnetic measurements, neutron diffraction experiments and X-ray photoelectron spectroscopy give evidence of such transitions.
