What is it about?
Can a spin-polarized current flowing through the sample change its magnetic properties? For example, the magnitude of its coercive force? Yes, it can but the effect can only be visible in critical links of a percolation cluster at low enough temperatures.

Why is it important?
If it can, it makes it possible to control the time or reliability of information storage in magnetic media.
