In two-dimensional electronic systems, at large values of the Wigner–Seitz parameter, an anomalous branch of magnons was found. In a quantum Hall ferromagnet state with ν = 2, the magnon dispersion reveals a magnetoroton minimum with depth dependent on electron density. Magnetorotons with opposite momenta are shown to attract each other.
