Ultrashort Spin Wave In A Nickel Iron Layer

Caption

An ultrashort spin wave (red) running through a nickel iron layer. Towards the center of the layer, the magnetic direction (blue arrows) swings only up and down in a sort of knot, while the motion in the other parts remains circular -- with opposing sense of magnetic rotation.
