Non-reciprocal magnons in a two dimensional crystal with off-plane magnetization
M. J. T. Costa, J. Fernández-Rossier, N. M. R. Peres +1
Non reciprocal spin waves have a chiral asymmetry so that their energy is different for two opposite wave vectors. They are found in atomically thin ferromagnetic overlayers with i…
