Dependence of the magnetic damping parameter on mutual orientation of magnetization in spin valves

What is it about?

We show that in Ferromagnet1/Normal metal/Ferromagnet2 (F1/NM/F2) spin valve like systems the relaxation rate of the F2 can be controlled by adjusting mutual orientation of magnetizations in F1 and F2 layers to be parallel or antiparallel without strong influence on the precessional frequency. Magnetization relaxation rate is an important parameter for spintronic elements, since it determines the speed of logic elements based on manipulation with magnetization.
