Can any of this be used for propulsion?
This is a science community covering a world class discovery and every fuckdamn comment is a meme or joke.
Fuck this community, blocked along with every yahoo in the thread.
We could make a science_serious kind of sublemmy for that kind of discussion, that way the playground stays and a more strict version would exist!
Or I could just give up lemmy too considering how new redditlike it has become in only 7 months
I feel like you are on some kind of phyrric crusade gl and I hope you’ll find peace with whatever troubles you man

Altermagnets are pretty interesting because their most defining feature is not the magnetic order in the materials. They look like ordinary antiferromagnets where the spins of adjacent atoms point in opposite direction and compensate each other, so no large magnetic fields are created. What differentiate altermagnets from antiferromagnets is how the electrons with different spin behave. When pulling current through altermagnets it will consist of purely spin up electrons along one crystal axis and purely spin down along orthogonal crystal axes. Thus the spin currents have a ‘alternating’ pattern, giving the name altermagnet. This is primarily exciting for the field of ‘spintronics’ which is all about creating technologies using spin currents.
Not all altermagnets are equally interesting, many antiferromagnets can be reclassified to altermagnets but they are generally insulating. (fun fact the first ever measured and textbook antiferromaget MnF2 is actually altermagnetic) So materials discovery of new altermagnets is important to find metallic, semi-metallic or even super conducting altermagnets.
Hmm yes, I understand.
