Using spin waves can efficiently generate spin current

Researchers from Cambridge University developed a more efficient way to generate spin current, using the collective motion of spins called spin waves (the wave property of spins). There are a number of different interactions in spin waves and the researchers's idea was to use such spin wave interactions for generating efficient spin currents.

One of the spin wave interactions (called three-magnon splitting) generates spin current 10 times more efficiently than using pre-interacting spin-waves.
