摘要: We demonstrate that chiral skyrmionic magnetization configurations can be found as the minimum energy state in B20 thin film materials with easy-plane magnetocrystalline anisotropy an applied magnetic field perpendicular to plane. Our observations contradict results from prior analytical work, but are compatible recent experimental investigations. The size of observed skyrmions increases anisotropy. use a full micromagnetic model including demagnetization and three-dimensional geometry find local (metastable) using numerical damped time integration. explore phase space system start simulations variety initial present systematic overview parameters for which metastable global (stable) states.
