    Physics aside, Chiral Altermagnon is a great band name.

    Some of the sexiest sounding sentences in research findings I have read. “ Their results showed direct experimental evidence of chirality – an asymmetric magnetic structure, akin to a spiral staircase or a screw – in the spins of an altermagnetic candidate material.”

    I appreciate the clarity that crystallizes in poetry that this author manages in their report!

      > Altermagnetic materials could be used to design advanced electronics, with applications including quantum technologies, memory devices and data centers.

      I liked this bit: low level devices and data centers — as if these are on the same scale

    Wait so this is distinct from antiferromagnetism how exactly, I thought the net-zero moment was the whole definition there?

      The paper’s abstract may answer your question. (see link above)

        In fact, I think you will find it is exceptionally clear writing. I think almost anyone can understand the differences and what is alter even with a quick read.

        After reading the abstract and intro, I personally have more questions than when I started!

    So Insane Clown Posse was right all along to question how fuckin' magnets work.

      I believe ICP was quoting Bill O’Reilly, though I suspect they also do not elucidate the matter any further.

    Maybe now we can fab a memristor for less than the cost of an entire used iPhone?

    We are so back (lol)
