The strong cobalt anisotropies in rare earth-cobalt intermetallics are shown to arise from orbitally selective 3d band energy dispersion due to either chain like or layered like cobalt staking rather than from usual crystal field effect. The magnetic anisotropies of itinerant electron systems are difficult to study in a complete theoretical model due to the great complexity of the collective ch...

Lanthanide and actinide intermetallic compounds display a wide range of correlated-electron behavior, including ferromagnetism, antiferromagnetism, nonmagnetic (Kondo) ground states, and so-called 'non-Fermi liquid' (NFL) behavior. The interaction between f electrons and the conduction band is a dominant factor in determining the ground state of a given system. However, lattice disorder can cre...

Mossbauer spectroscopy has been used to study both the physics and phenomenology of hydrogen absorption in rare-earth intermetallics. This paper surveys experiments that have been carried out so far, and discusses the results obtained. * * * * * * * * LaNi5 and similar intermetallic compounds have been of great interest recentlyl because of their ability to absorb reversibly large amounts of hy...
