Rare-earth-free permanent magnet candidate system. WIP
Mostly giving up on this system. It doesn't seem like it has what we're looking for given the few I've tested and the stability of the symmetries we're looking for.
Learned that Sn likes to form some really strange looking crystals. Unfortunately it didn't look like any of them are relevant to permanent magnets.
22 meV above the hull

MAE: 0.1527
67 meV above the hull
MAE: 0.199
Just because there were a lot of them, let's look at the Fe-Sn phase diagram so we can see better what's happening there.
Strange one! They really don't like to go together. Not that they wont, but it's going to take some energy!
