what
@alina ur not far off! “spintronics” is a real thing and people have made microchip-like logic gates using magnetism it’s cool
@helical @alina okay so magnetic thinking machine when
@helical @alina
And that's a rabbit hole that will absorb me in a few days ... Thanks for the nerd sniping !
@helical
Can I bother you for more stuff on the matter ?
You manage to tickle my 'tism just right, and now I want to know more !

If you have some resources on this, it would be really cool !
@jaggi unfortunately I really don’t know that much about it, but a lot of the designs including the one in the picture are based around “skyrmions” which are disturbances in the force patterns in magnetic fields that kind of act like particles because they’re topological, the magnetic field is twisted up and that twist can’t just go away

imagine like a strip of paper held firm on either side, if you grab the middle and twist it you can move around a half-twist on one side (a “””skyrmion”””) and the half twist on the other side (an “””anti-skyrmion”””) the magnetic ones are basically 3D magnetic field versions of this, and you can control their movement in certain materials

particle physicists also talk about a different skyrmion in like different fields which is kinda confusing these are specifically magnetic skyrmions

the idea of moving individual skyrmions along paths and having them interact to store information or make logic gates is from the 2013 Fert paper and called “racetracks” which makes everything sound extra cool :3
@helical @jaggi Also some materials will naturally form a lattice of skyrmions just by themselves which isn’t majorly useful for spintronics stuff but is very fun and this one miiiight just be working on trying to diy such a material and making a yt video about it :3
@re @helical
Gosh your both really good at this infodumping thing !

I'll save this paper in my "to read" pile (it got pretty figures !)
And I'll see what my dumb brain can gather about this !

Thank you both (and I will follow that cute YT channel :3)

@helical @jaggi awww thanks :3

I haven’t done stuff on it since I’m doing internship this summer but end of august I can get back to it :)
