High temperature singlet-based magnetism from Hund’s rule correlationsAccording to a statement from the researchers responsible for the USb2 discovery, physicists had long suspected that groups of spin excitons might cluster together with their magnetic fields oriented the same way. They called the effect "singlet-based" magnetism. The phenomenon was previously proven in brief, fragile flashes in ultracold experimental settings, where the strange physics of quantum mechanics are often more pronounced. Now, physicists have shown for the first time that this sort of magnet can exist in a stable way outside of supercool environments. In the compound USb2, magnetic fields form in a flash and disappear almost as quickly, the researchers reported in a paper published Feb. 7 in the journal Nature Communications.

Physicists Found a Brand-New Kind of Magnet Hiding in a Uranium Compound
Even the older non-nuclear applications of uranium and thorium have been given up by raising the bogey of radioactivity. Uranium salts are no longer used to Colorado glass. Thorium mantles have also been given a bad name.
