The easy read:
Altermagnetism: A new type of magnetism, with broad implications for technology and research
"...Altermagnets have a special combination of the arrangement of spins and crystal symmetries. The spins alternate, as in antiferromagnets, resulting in no net magnetization. Yet, rather than simply canceling out, the symmetries give an electronic band structure with strong spin polarization that flips in direction as you pass through the material's energy bands—hence the name altermagnets. This results in highly useful properties more resemblant to ferromagnets, as well as some completely new properties..."
The paper:
Altermagnetic lifting of Kramers spin degeneracy
This is out of my depth and not a 'rabbit hole' I have the time for, but I am aware of motor and ctlr builders here and think this might be of interest to some them?
