Could a Magnetic Sandwich Make Your Electronic Devices Work More Efficiently?

Caption

Four layers of a surface-conducting material (Bi2Te3) between two single layers of a magnetic insulator (MnBi2Te4). This structure creates the conditions to align the manganese spins (red arrows) and support a zero-resistance, spin-polarized current.
