How do they function and what are their appliances?

They currently don’t really work and have no real world applications as we can’t reliably make them at scale
A normal Field Effect Transistor has it’s behavior adjusted by changing how many electrons are on the gate and thus the electric field in the transistor. You can turn it full on, full off, or carefully hold it at some intermediate level
Spin transistors rely on magnetism. It’s not obvious from the name, but something becomes magnetized when the spin of it’s electrons gets aligned and isn’t random. These transistors would be able to hold their state without power and could be checked on without power enabling lower power devices
Unfortunately, one of the few similar applications is MRAM(magnetic ram) and it brings back susceptibility to magnetic fields
