Compound may magnetically outperform neodymium magnets:
NIMS and Tohoku Gakuin University have developed a boron-doped anisotropic Sm(Fe0.8Co0.2)12 thin film containing only small amount of rare earth elements. The compound exhibited 1.2 tesla coercivity, sufficient for use in automotive electric motors. This was achieved by creating a unique granular nanostructure in which Sm(Fe0.8Co0.2)12 grains are uniformly enveloped by an amorphous grain boundary phase approximately 3 nm in thickness. This compound exhibited superior magnetic properties to that of Nd-Fe-B based magnets even when processed into a thin film.
Demand for green technologies that can help to reduce CO2 emissions (e.g., electric motors for environmentally friendly vehicles and wind power generation) has been growing, leading to rapidly increasing demand for the high-performance permanent magnets needed for these technologies. The Nd-Fe-B based sintered magnets currently in use are composed not only of the rare earth element neodymium but also a heavy rare earth element: dysprosium. Because of the geopolitical risks associated with the acquisition of these materials, development of new magnets that do not rely on the scarce elements is desirable.
It is hoped the compound can supply green technologies with less geopolitical risk than neodymium magnets.

And as you well know you have, in earlier posts, advocated that some of those you object to should 'be shot'. Does that sound like an 'extremely moderate' expression of how someone should be treated? In a more temperate moment, referring to people that you again disliked, you encouraged community members to simply 'punch them in the face'. Both those submissions were rejected for the extremist views they advocated.
Apologise to you? - your problem is that your memory is failing. When you criticise Runaway for his extremist views it is a perfect example of the pot calling the kettle black. While you may have moderated some of your more recent posts you seem to have forgotten your transgressions of only a few years ago. I haven't.
You can stick your claims of having 'extremely moderate' positions where the sun don't shine.

Shot, maybe, but not killed! And not "people I disagree with"?, only Nazis, which is an extremely moderate position, considering they are actual, even if "neo" Nazis. You overreact at my rhetorical mirroring of calls for violence, and you, of all people, with your background, should be aware of my moderate extremeness. A perspective of millennia can do that to a person.

Offtopic, per offtopic, eh, Tu quoque? Even if it is the moron redneck hillbilly cow-fucker Runaway administering the mods, you are ultimately responsible, janrinok. Unlimited liability, such as it is on SoylentNews. Accept it like a man.
