  text: Partially filled Landau levels host competing electronic orders. For example,
    electron solids may prevail close to integer filling of the Landau levels before
    giving way to fractional quantum Hall liquids at higher carrier density1,2. Here,
    we report the observation of an electron solid with non-collinear spin texture
    in monolayer graphene, consistent with solidification of skyrmions3—topological
    spin textures characterized by quantized electrical charge4,5. We probe the spin
    texture of the solids using a modified Corbino geometry that allows ferromagnetic
    magnons to be launched and detected6,7. We find that magnon transport is highly
    efficient when one Landau level is filled (ν=1), consistent with quantum Hall
    ferromagnetic spin polarization. However, even minimal doping immediately quenches
    the magnon signal while leaving the vanishing low-temperature charge conductivity
    unchanged. Our results can be understood by the formation of a solid of charged
    skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay.
    Data near fractional fillings show evidence of several fractional skyrmion solids,
    suggesting that graphene hosts a highly tunable landscape of coupled spin and
    charge orders.
