(color online) (a)–(d) Magnetic domain dependence on temperature at 50 mT (e)–(h) Biskyrmion density dependence on the different magnetic fields while FC process. (i)–(l) Biskyrmion distribution after increasing the magnetic field to complete skyrmion state based on panels (e)–(h). The experimental procedures are shown on top of the column.
