Magnons (IMAGE) Johannes Gutenberg Universitaet Mainz Caption An electrical current excites the superposition of two magnons with linear polarization (indicated by the red and blue arrows). Subsequently, energy is transported through the antiferromagnetic insulator. This can be detected as electrical voltage.
