>>10150206Look into spintronics. Essentially it’s layering magnetic material with non magnetic material, there will be a spin-spin interaction through the non magnetic material, as well as things like tunneling of electrons and such. So, you do it right, you can control all the spins in the magnetic material.
The idea is rather simple, but if you understand anything about computers, you’ll understand why this is really an interesting tool. Solid state memory can be made much smaller and far more efficient, or even non-volatile RAM, etc. Chips use the tech now, that’s why they’re as small as they are, but the field is only like 20 years old, so it’s a land of opportunity for anyone who can understand quantum and materials.
