Damping Illustration (IMAGE) University of Minnesota Caption University of Minnesota-led research discovered that the interaction between magnetism and sound particles in spintronic devices can lead to damping, or the loss of energy, a process depicted in the figure above. The finding will ultimately allow engineers to develop more efficient spintronic devices in the future.
