Fig. 2: The creation process of an isolated skyrmionium.
From: Reversible conversion between skyrmions and skyrmioniums
a–f The creation process of the isolated skyrmionium. The sinusoidal pulses are injected into the Hall bar along +x by default. g–n The transition from the stripe domains to the isolated skyrmionium. The dashed line represents the stripe domains that disappear after the sinusoidal pulse.
