Long-time variation of magnetic structure in rare-earth intermetallic compounds

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...

First Investiation of magnetic ground states in the rare - earth intermetallic compounds

We report the magnetic properties strongly varying with the rare-earth elements in the newly found ternary compounds RAl0.9Si1.1, which crystallize in the tetragonal α-ThSi2-type structure. For R = Ce the alloy has a weak ferromagnetism below 11 K and for R = Pr it orders ferromagnetically at 17 K, while for R = Gd it is antiferromagnetic with TN = 30.5 K. In addition, we find no field effect o...

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.

Theoretical screening of intermetallic ThMn12-type phases for new hard-magnetic compounds with low rare earth content

We report on theoretical investigations of intermetallic phases derived from the ThMn12-type crystal structure. Our computational high-throughput screening (HTS) approach is extended to an estimation of the anisotropy constant K1, the anisotropy field Ha and the energy product (BH)max. The calculation of K1 is fast since it is based on the crystal field parameters and avoids expensive total-ene...
