I know the usual way uses oscillating magnetic fields and it being very cold. There are other ways i'm not familiar with. I'm a classical computer engineer not a quantum computer engineer. I'm more used to energy bandgap then spin control.

Good thing talking is a free action.
Warhammer 40k. I'm still a part of it. There are some cool and smart people in it.
But there are also a large group of raceist, misogynist, jerks. Then there are the people who are incredibly annoying to play against because of poor social skills. There is always at least one guy who really needs a shower.
This is a bit outside my field. That said I don't think so.
The overall crystal should be very weakly magnetic. You want strong magnet with a high flux density so the electric field can push or pull against it.
I think this would be more useful in quantum computing as you get two bits polarity and spin. Or high density storage.
But who knows. There are clever physicists out there that know a lot more about this. They presumably see many more possibilities then I do. If the effect can be interrupted you could stitch between states. Like turning a magnet on and off. That would have uses like you described.
This article is a mess and badly written.
Basicly magnetism comes from electron spin orientation. There are two well known spin configurations.
Ferromagnetism: there is at least one electron with a spin that isn't paired with an opposite spin electron. That atom then has a north and south magnetic pole. Like iron. Arrange all the atoms pointing the same way and you have a refrigerator magnet.
antiferromagnetism: all the electrons in the atom are paired with an opposite spin election. It's complicated but basically they couple together and there isn't a magnetic pole outside the atom. Like in copper.
Altermagnetism: what this article is about. You have a crystal of atoms with an unpaired electrons. The crystal would normally be ferromanetic. However they are arranged in a regular set of pairs that cause the electron spin to cancle out. Think of a checkerboard pattern where each white square cancels a black square next to it.
The antiferromagnetism and altermagnetism both have the spins cancelled out but the mechanism is different so there are different properties. Kramers degenerate vs wavevector.
In theory this gives you an extra state spin. So a magnetic drive uses a pattern of north and south to encode information. Ie NNSN becomes 0010.
With this you have north, south but also spin left, right. So you can encode more information.

I'm not the person you were responding to but here is why I agree with them.
He makes disingenuous arguments and misleading edits in his films. He edits speeches together to misrepresent what people said. Lies about things like having his mic cut. Makes up or misrepresents statistics Etc.
I usually somewhat agree with his overall position but if I didn't his films and speeches would never change my mind.
He is about as trustworthy as Dinesh D'Souza just with a different political agenda.
I've herd it called passive-progressive.

I love jokes that are one huge setup. The series in general is great for that as each episode starts with an absurd but accurate recap.

In the sense that it's two different but similar states.
I'm pretty sure we can say it's not actually spin now. Electrons have a charge and a magnetic field. If they are charged and spinning that world generate a magnetic field. So spin was used to describe the orientation of the field. The name for the state stuck
