Rare earth magnets, like that of Neodymium-iron-boron, are used in sensors, and even ferrite magnets contain small amounts of rare earths and minor metals like Lanthanum and Cobalt to improve magnet performance by as much as 25%. GPS navigation, touch screens, power windows, and all the hi...

These rare-earth oxides are used as tracers to determine which parts of a watershed are eroding. Clockwise from top center: praseodymium, cerium, lanthanum, neodymium, samarium, and gadolinium. (Image credit: U.S. Department of Agriculture / Peggy Greb.) Rare earths – which include exotic-...
[...]a glance at the US Geological Survey (USGS) interactive map of October 2014 shows that many rare earths are anything but rare - outside most of Western Europe, deposits can be found in abundance almost everywhere. [...]from the 1960s through to 2002, California's Mountain Pass ...
Rare earths refer to a set of17 chemical elements(scandium, yttrium and the fifteen lanthanides). Contrary to what their name seems to indicate, rare earths are no more rare than other more common metals: their concentration in the earth's crust is, for example, higher ...
Four years ago, some manufacturers worried that they would run up against a shortage of rare-earth elements, which are used to make wind turbines, certain light bulbs, computers, and many other high-tech products. Rare earths actually aren’t rare, but they are found in low concentrations, ...

TRUMP SAYS MINERALS DEAL HAS BEEN 'PRETTY MUCH' NEGOTIATED WITH ZELENSKYY, MEETING SLATED FOR FRIDAY What are rare earths? Rare earth minerals aren't necessarily rare in the sense that there are few of them, but rather they tend to occur in relatively small quantities or are mixed with ...
Rare earth metals exhibit rich and widely investigated magnetic behavior in the bulk. Comprehensive reviews are offered by Elliott (1972), Coqblin (1977) and Jenson and Mackintosh (1991). The 4f core electrons remain distinct from the conduction states and couple according to Hund's rules to ...
Rare earthsare a group of more than a dozen metals, much less abundant than titanium or lithium, that are used in many high-tech sectors, including green energy, electronics and aerospace. Ukraine has substantial reserves that are mostly untapped, and it is unclear how expensive they would be...
