Cobalt site preferences in iron rare-earth-based compounds

rtupmtni Adrni OXYGEN STABILIZED RARE-EARTH IRON INTERMETALLIC COMPOUNDS*

A new, oxygen-stabilized intermetallic compound was identified in sintered, pre-alloyed rare-earth iron powder samples. Its composition corresponds to formula R.-Fe^Oj, and its crystal structure belongs to space group Imjnu The presence of these compounds has been observed, so far, in several K-Fe-0 systems, with R = Gd, Tb, Dy, Ho* Er and Y.

Origin of Cobalt Anisotropy in Rare Earth-cobalt Intermetallics

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...

Quadrupole Interactions in Rare-earth Intermetallic Compounds

A survey of the role played by the one-ion magnetoelastic and two-ion quadrupolar interactions on the magnetic and elastic properties of the rare-earth intermetallic compounds is given. These couplings are present in numerous systems and manifest themselves through a great variety of effects. The study of the multipolar interactions concerning the 4f shell has known a great development about ra...
