Erbium-based magnetic refrigerant (regenerator) for passive cryocooler
A two stage Gifford-McMahon cryocooler having a low temperature stage for reaching approximately 10K, wherein the low temperature stage includes a passive magnetic heat regenerator selected from the group consisting of Er.sub.6 Ni.sub.2 Sn, Er.sub.6 Ni.sub.2 Pb, Er.sub.6 Ni.sub.2 (Sn.sub.0.75 Ga.sub.0.25), and Er.sub.9 Ni.sub.3 Sn comprising a mixture of Er.sub.3 Ni and Er.sub.6 Ni.sub.2 Sn in ...
متن کاملQuadrupole 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...

متن کاملThe regenerator location problem
In this article, we introduce the regenerator location problem (RLP), which deals with a constraint on the geographical extent of transmission in optical networks. Specifically, an optical signal can only travel a maximum distance of dmax before its quality deteriorates to the point that it must be regenerated by installing regenerators at nodes of the network. As the cost of a regenerator is h...
متن کاملrtupmtni 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.
