[Figure 2] Schematic of the principle of 'spin loss' based magnetization control

Caption

Structure illustrating the new principle of self-reversing magnetization direction through spin loss when a current is applied inside a magnetic material. When current flows, spin is generated inside the magnetic material, and some spin escapes in the direction of the antiferromagnet on the right. Normally, this escape of spin is considered a "loss," but in this study, this loss creates the same effect as spin entering the magnetic material, which is what drives the magnetization to reverse itself. In particular, as shown in the figure, the more spin that is lost, the easier the magnetization switch occurs. In other words, it becomes easier to change the magnetization.
