...This research is on the interface between inorganic chemistry and organic chemistry," Evans says. It makes use of transitional elements of the periodic table such as nickel, samarium, boron, rhodium and iridium...
...women who are loath to have their ears pierced, there is a new, no-bore way to wear earrings that nestle close to the lobe without clips. A magnetized earring is held in place by a minute cobalt-and-samarium magnet on the invisible side. Price: from $7.50 to $25. One trouble is that in telephonic or amatorial exercise the quarter-inch magnet is as easy to lose as a contact lens; some stores, like Saks Fifth Avenue, will remagnetize the lady without charge. No questions asked...
...several years, Bell scientists have been experimenting with thin wafers of crystalline materials known as orthoferrites, which are compounds of iron oxides and such rare-earth minerals as ytterbium, thulium and samarium-terbium. They found that when a strong enough magnetic field is applied, orthoferrites display an extraordinary property: tiny cylinder-shaped areas, or "bubbles," of magnetism are formed in the wafer, their polarity opposite to that of the surrounding material. Often smaller in diameter than a human hair, the magnetic bubbles can be maneuvered and positioned into an almost endless variety of patterns...
When he came to scrutinize Nos. 60 and 62, two metallic members of the gathering, named Neodymium and Samarium respectively, he detected a presence fainty visible between them. Bringing them further out into the open-he was working with X-rays and used delicate refining methods to isolate the two metals that he wished to examine more closely-he clearly beheld this intervening shadow. It appeared in the wavelength spectra of Nos. 60 and 62 as a line that belonged to neither yet was identical in both. Forthwith, though he had no lump of new metal in his hand...
