And if not for that word, the article would be completely unexciting. You found that you can make magnets out of multiple materials? We already knew that. If the materials aren’t abundant/cheap and easier to manufacture then this isn’t a story. And neither of those claims are tested or verified in this. So this isn’t a big deal.
This is a magnetic semiconductor (and antiferromagnetic). All non-experimental magnetic semiconductors require cryogenic temperatures. If this pans out (works, cheap-ish to produce), it could mean significantly faster memory, with significantly less energy usage and significantly less waste heat (and thus, even less energy usage).
Obviously it's very far from "panning out", but "room temperature" is not a given here. It's not normal, and it would be a huge deal.
"Whereas traditional electronics are based on control of charge carriers (n- or p-type), practical magnetic semiconductors would also allow control of quantum spin state (up or down). "

That page lists a bunch of other stuff too.
Wikipedia seems to say it is new, assuming this one has "robust" coexistence of the properties the framing would be important and not just thrown in there to trick people into thinking it was about superconductors:
> To date, GaMnAs remains the only semiconductor material with robust coexistence of ferromagnetism persisting up to rather high Curie temperatures around 100–200 K.
If there is an important combination of material properties that previously was only available at cryogenic temps, a room temp version is significant since you don't need cryogenic cooling to take advantage of it.
That's not really true, I think. (assuming you're talking about "hallucinations" in the sense of the LLM behaviour, not the original meaning of the word)
I was just talking about LLM hallucinations with someone the other day, when doing a brainstorm or discussing ideas, complaining how the confidence with which hallucinations are presented, often led me on wild goose chases that waste my time for an hour or two.
When I realized that, for all the "how is that different from what humans are doing", I have never EVER experienced such kind of confusion with another real human.
And in fact were someone to behave that way, I'd be thoroughly creeped out (you know, the feeling you get when the person across you turns out to be an empty shell of a psychopathic mind, kind of creeps) and do my best to keep them out of my personal circle and avoid having to interact with them ever again.
There is still something in interaction between actual humans, that creates a level of understanding, that LLMs simply cannot (yet?) simulate. There is a certain (deep, unspoken, not language-based) understanding of "this is the other person's goal", instead of "I'm scoring imaginary talking points by talking to them".
And you know the type of person who actually does that, talking bullshit very confidently to "score points", that behaviour is generally considered adversarial and unaccepted between peers, and keeping it up after being discovered to consistently attempt that behaviour, with real humans often results in social exile.
(btw I'm not sure if it's inherent in LLMs that they can't learn this, maybe they can, but my point is that, right now, they are definitely not trained to do this)
