Image: (Left) The traditional setup applies current around the edges of a magnet to create spins that enter the magnetic material. However, during this transfer, some spins are lost, lowering the efficiency of realigning the magnet's orientation. (Right) The new approach highlighted in this study involves directing current straight into the magnetic layer, where spin disperses in a single direction. This escaping spin acts back on the magnet like a push from the other side, effectively
